1. simplify the square root (it's a: - sign in front of the s. r. symbol
–0.5
5
–5
–25

Given:  

First, just leave the negative sign at the side. You will deal with that later. For now, you focus on solving on the square root of 25. The square root of 25 is a number that when multiplied with itself, equals to 25.

For example, 4x4=16. So, the square root of 16 is 4.
Now, for 25, the answer would be 5. Since 5x5 = 25.

Then, you take the negative sign with the 5. The answer would be -5.
