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

What is an example of a rational number between the negative square root of four and the square root of four?
-1,0,or 1 the negative square root of four is negative two and the square root of four is two
What is the difference between a positive and negative square root?
The positive square root of a number is the non-negative value that, when multiplied by itself, equals the original number, while the negative square root is the negative counterpart of that value. For example, the square roots of 9 are +3 and -3, where +3 is the positive square root and -3 is the negative square root. In mathematical notation, the positive square root is often denoted as √x, while the negative square root can be expressed as -√x.
What 2 numbers would be the square root of 53?
Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.
What is equal to square root of -8?

Why cant you evaluate the square root of negative twenty five using real numbers?
using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number

How can you tell when to put the 'positive and negative' sign when you square root something?
The square root is generally positive or negative and it is only the context of the question that will tell you whether it is the positive root or the negative root. For example, if you are solving for the lengths of the sides of a square, a negative measure makes no sense so it must be the positive root.
What 2 numbers would be the square root of 53?

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
What is the negative square root of 100?
The square root of 100 is 10 but positive and a negative is a negative so it is negative 10
Is negative square root of 21 irrational?
Yes, as is the positive square root.
What is the square root of a square?
√(a^2) That is |a| (the absolute value of a) Because if a is positive, a^2 is positive, and since √ is a positive square root, √(a^2) is a. If a is negative, a^2 is positive, and since √ is a positive square root, √(a^2) is -a. So if a is positive, √(a^2) is positive (which is a) If a is negative, √(a^2) is also positive (which is -a) So √(a^2) is |a| for every a.
What is equal to square root of -8?
Positive or negative (√8 * i) = Positive or negative 2.828i
What is a principal square root?

What is the nonenegative square root of a number?
Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.
