Answer 1

(e) -√125 = -5√5, not an integer

Explanation:

You want to identify the numbers that are not integers.

Negative square root

The positive or negative square root of a perfect square will be an integer.

• -√1 = -1
• -√324 = -18
• -√100 = -10
• -√25 = -5
• -√125 = -5√5 . . . . . not an integer
