Is a square root of a negative number a real number?
no, it is an imaginary number represented by an i. For example, the square root of -4 is 2i.
Is the square root of any real number always positive?
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
Is the square root of -4 irrational?
The square root of -4 is not irrational, it is imaginary. Irrational numbers are numbers that cannot be expressed as a fraction, like the square root of 2. Irrational numbers, however, are a subset of real numbers. The square root of -4 however, is not even a real number because no real number, when squared, gives -4. Therefore the square root of -4 is an imaginary number.In calculus, the root is expressed as 2i where iis the square root of -1.
Is the square root of negative 4 irrational or not real number?
It's irrational/not a real number
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.
Is non-real numbers exist?
no, every number is a real number --- There are numbers that are not real numbers. They are called imaginary numbers, and have the property that when they are squared, the result is negative. The square root of -1 is called i, and the square root of any other negative number is i times the square root of the absolute value of the number. So the square root of -4 is 2i.
Is the square root of negative four positive and negative?
no, it is actually not a real number. It falls under the category of a imaginary number which is the square root of -1 or as the variable i Because the square root of -4 is 2i because the square root of 4 is 2 and if you take i out it will maek it a positive so it goes like this -4 SR= 2i -9 square root= 3i and so on
Is the square root of 8 the number 4?
No. The square root of 16 is 4.
How do you get square root of 16?
A square root of a number is a lesser number that when multiplied by it's self equals the larger number. The square root of 16 is 4. 4*4=16
What is the difference between finding the square root of a number or finding the square of a number?
The square of number is a *a ( a number times itself ). For example, 4*4=16, so the square of 4 is 16. the square root is the number before you square it. The square root of 16 is 4. It actually simple to remember this way: think of the root as the root of a tree, growing to multiply itself.
Is the square root of 4 a rational or irrational number?
The square root of 4 is 2 which is a rational number
Is the square root of a negative number positive?
No. To find the square root of any number, you try to find what number, multiplied by itself gives you that number. For instance, I know the square root of 16 is 4, because 4*4 gives me 16. If I wanted to find the square root of -16, I cannot think of any number, multiplied by itself to give me -16. 4*-4 works. -4*4 works. But since they are NOT the same, I don't get an answer. Your real answer will be an imaginary number. Therefore, it isn't positive or negative.
