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 256 is 16, giving us an answer of 5/16. However, as we can see, there is a negative outside of the square root. This means that we multiply 5/16 by -1, giving us our final answer: -5/16.
