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 121 is 11, and the square root of 16 is 4, giving us an answer of 11/4. However, as we can see, there is a negative outside of the square root. This means that we multiply 11/4 by -1, giving us our final answer: -11/4.
