What does square root mean?
It is the number that is multiplied by itself to get another number.For example, what number do you multiply by itself to get 25?The answer is 5, because 5 multiplied by itself is 25.Another way to say 5 x 5 is 'five squared', written as 5225 (i.e. the result of 5 x 5) is 'the square' of 5.And 5 is the root, the 'square root' of 25.What might be the square root of 9? (3, because 3 x 3 = 9)So what is the square root of 49 ?
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!
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 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
How do you find square root on a calculator?
To find the square root of a number on a calculator, you typically press the square root symbol (√) key followed by the number you want to find the square root of. Some calculators may require you to enter the number first and then press the square root key. The calculator will then display the square root of the number you entered.
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.
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.
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.
What is the square of root 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.
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 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.
What does square root mean?
It is the number that is multiplied by itself to get another number.For example, what number do you multiply by itself to get 25?The answer is 5, because 5 multiplied by itself is 25.Another way to say 5 x 5 is 'five squared', written as 5225 (i.e. the result of 5 x 5) is 'the square' of 5.And 5 is the root, the 'square root' of 25.What might be the square root of 9?

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.
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
What is the square root formula?
The formula of square root is basic once you learn it. To figure out the square root of a number you must know what a square number is. A square number is the product of a multiplication problem such as 7x7, 123x123 and 14x14. So the square root of 7 is 49. A trick to figuring out the square root of a number is adding consecutive odd number to the previous problem.
