Answer
-5/9
Work Step by Step
When taking a square root of a fraction, we take the square root of the numerator (top of the fraction) and denominator (bottom of the fraction) separately. The square root of 25 is 5, and the square root of 81 is 9, giving us an answer of 5/9. There is a negative in front of the square root, so we make our answer -5/9.
