Is the root of an even number equal to an even number?

If you mean square root when you say 'root'then... Yes, only the same number can be a square root and the factors of an even number must contain at least one even number So, if one of the roots is even then the other is the same number and is therefore even.

Can a perfect square have a negative square root?

If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.

A short note on square root of rational number?

Square root of a rational number may either be rational or irrational. For example 1/4 is a rational number whose square root is 1/2. Similarly, 4 is 4/1 which is rational and the square root is 2 which of course is also rational. However, 1/2 and 2 are rational, but their square roots are irrational. We can say the square root of a rational number is always a real number. We can also say the rational numbers whose square roots are also rational are perfect squares or fractions involving perfect squares.

What two numbers multiplied together equal 31?

What you are trying to say is "What is the square root of 31?" Well the answer is "undefined" because the square root is not a whole number.

The inverse of squaring a number is finding the?

Square root. Except that it is not quite as simple as that. If you start with a negative number, say -3. Square it to get 9. Then find the square root: should you go for -3 or +3 as the square root? Unless you knew what the original number was, the "inverse" may not take you back to the starting point!

Why is the square root of any real number is always sometimes or never positive?

Sometimes.The square root of a positive number is positive.The square root of zero is zero.The square root of a negative number is a complex number - if you want only real numbers, you can say that it is undefined, and many calculators will give you an error message.

What is the square root of X?

That depends upon the value of X. The square root of any number (X) is a factor of that number that, when multiplied by itself, yields the number. For example, 3 is a factor of 9 that when multiplied by itself (3 x 3) yields 9. We say, therefore, that the square root of 9 is 3.

What is the squared root of 9?

The square root of 9 is 3. If s is the square root of a number, n, then sxs=n. In other words, the square root of n is just asking, find a number that you can multiply by itself and obtain n. The concept can be generalized to cube roots, where we say find a number multiplied by itself 3 times.

Where do you find square roots?

say u have the number 16. Its square root is 4. the square root(4) is the number that, when multiplied by itself, gives the original number (16). To find a square root you must first find the two closet perfect squares (a square being the product of a square root, a perfect square being the product of square roots that are whole numbers 1,2,3,4, ect.) then u find the approxomate distance between

The Square root of 47 is between which two whole numbers?

To figure this out, I always start with square roots I know, and that are close to 47. So, first, I would figure out that the square root of a number such as 36 is 6. The square root of 49 is 7. Now, since there are no other whole numbers between 6 and 7, and the square root of 47 falls between the square root of 36 and 49, we can say that the square root of 47 is between the whole numbers 6 and 7.

How is a square root and square number related?

Yes, they are! For instance, let's say you have √2. (√ is the symbol for square root incase you were unsure - don't mean to offend you.) Now, if you were to square the square root of two, (√2)², it would equal 2! Also, you can "undo" powers with square roots, and vice versa! For example, √9 = 3 and 3² = 9! Another one is, √4 = 2 and 2² = 4. Hope this helps!

What is the square root of 48AB to the power of 2?

if you're squaring a square root, your're getting the number back. lets say it was square root (49)2 the square root of 49 is 7, 7 2 is 49 if you do it the other way 492=2352, this square root is 49, so the answer is 48AB

Why is i one of the solutions to the equation x2 equals -1?


Is the square root of 11 a whole number?

It is true that the square root of a prime number like 11 is never a whole number. But to say that that has never been proven is incorrect. The square root of any positive integer that is not a square number (the square of an integer) is always irrational, and that is relatively easy to prove. To prove that prime numbers are not square numbers is even easier. That is basically true by definition. If a number greater than 1 were a square number, its square root would be a factor other than 1 and itself; therefore, it would not be a prime number.Answer 1No - the square root of 11 is not a whole number. 11 is prime so it has no factors except itself and 1, anyways.Any prime number has no square root that is a whole number or integer. (That postulate has not been proven, but it has not been disproven so it is accepted as true.)

What is an imaginary number?

The square root of a negative real number is an imaginary number.We know square root is defined only for positive numbers.For example,1) Find the square root of (-1)It is imaginary. We say that square root of (-1) is i.In fact they are not real numbers.2) Find the square root of (-4)-4 can be written as (-1)(4)Square root of 4 is 2 and square root of (-1) is iSo, the square root of -4 is 2i.Similarly, we can find the square root of other negative numbers also.Source: www.icoachmath.comAn imaginary number is defined to handle square roots of negative numbers. The imaginary unit i is defined as the 'positive' square root of -1.

HOW to take out fourth square root of a NUMBER?

The fourth square root is the 16th root of a number. On a computer, to find the 16th root of a number, say 5.6, enter 5.6^(1/16). If the number you start with is positive, you will have 2 real roots (one positive and one negative) and 14 complex roots. If it is negative, you will have 16 complex roots.

Why is square root called square root?

When you square a number, you are referring to the area of a square, where the number you are squaring is a side length. The square root is a method of finding a side length when you know the area. Ans-2: because that is the root element. Say sq.root(4) --> 2, because 2 is the fundamental element on which it was built. Same goes for cube root. cube.root(8) is 2 because again here this is the fundamental element on which it was build.

Square root symbol?

√ this is the symbol for square root. So if you take a number, say n, then √n means the square root of n. This of course means that is √n=m, where m is some number no necessarily different from n, then n2 =m For example √36=6 but √1=1

What is square root of 28?

technically the square root of 28 is to hard to find because it would go on and on, so most math maticians say that the answer to the square root of 28 is the square root of 28.

How do you find the principal square root of a monomial?

Say the monomial is 4a squared. To find the square root to must do each part seperately. So square root of 4 is 2 and the square root of a-squared is |a| because we do not know the sign of a. The answer is 2|a|. If there is anything that cannot be "square rooted" then it would stay under a square root sign and just multiply by 2a as well. The principal root of a number is only its positive root (you can understand that you are looking for the principal root from the sign in front of the radical, which is a positive one)

A square root of a number is one of its two equal factors?

That is correct. I would say, the square root of a number is another number that, when you multiply it by itself, gives you the number you started with. Remember that a positive number always has two square roots, one positive and one negative. The square roots of 49 are 7 and -7, since 7x7=49, and also -7x-7=49.

How do you find the square root of a square root?

The laws of exponents help you out here. We can write square root of a number n, as n^1/2 power. Now we know that raising and exponent to a powers is done according to the rule (a^b)^c=a^bc. That is two say we multiply the exponents So doing that with 1/2 each time we find that the square root of the square root of n is n^1/4 which is the 4th root of n Looks look at an example. let n=16 The square root is 4 and the square root of that is 2 So this means the 4th root of 16 must be 2, but 2x2x2x2=16 so it is! Using this, one can you 1/4 as the exponent on a calculator and find square roots of square roots. or you could just find the square root of the first number then find the square root of that... real simple.

What is the square root of -9 times the square root of -9?


How do you square both sides of a square root equation?

Easy. Say I was going to do ____ \/ 2 =1.41.... So then you square the left side 2=1.41.... And then you square the other side 2=2 (When you square root a number and you square it, you end up with the original number)

What is the square root of a chicken?

First of all, let say we have a square with the side of a. We have the area of the square is a2 (a*a). In other words, the square root of the area of that square is a (square root of a2 is a). To calculate the square root of a chicken, what you need to do is to crush the chicken and shape all that crushes into a square. Based on the idea of the square above, since the whole chicken is the area of that square, the length of a side of that square would be a square root of a chicken. There you have it.
