What is not a real number square root?
Zero has one square root which is 0. Negative numbers don’t have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers.
How do you tell if a root is a real number?
Every positive real number has two square roots, one positive and one negative. For this reason, we use the radical sign to denote the principal (nonnegative) square root and a negative sign in front of the radical – to denote the negative square root.
How do you know if a square root is irrational?
If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).

Is 23 a perfect square?
Is 23 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 23 is about 4.796. Thus, the square root of 23 is not an integer, and therefore 23 is not a square number.
