Answer with explanation:

The value of square -9 is not -3 ([tex] \sqrt { - 9 } \neq - 3 [/tex]).

It is because we cannot take a square root of a negative number since any number multiplied by itself is a positive number so you never get a negative value.

Therefore, it given an error if you try to take a square root of a negative number on a calculator.

Answer:

The value of √-9 is not -3 because we cannot take the square root of negative numbers

Step-by-step explanation:

It is not possible to take square root of a negative number.

If any positive number we can take its square roots.

-9 is a negative number.

√9 = ±3 means that,

√9 = 3 or √9 = -3

3 * 3 = 9 and -3 * -3 = 9

Therefore the value of √-9 is not -3
