Answer

-1/3

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 9 is 3, and the square root of 1 is 1, giving us an answer of 1/3. However, there is a negative in front of the square root, so we make our answer -1/3.
