Answer
$2\sqrt{6}/5$
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 there is no integer square root of 24, giving us the expression of $\sqrt{24}/5$ However, we know that 4, which is a perfect square, is a factor of 24. Thus, we can simplify:
$\sqrt{4}\sqrt{6}/5=2\sqrt{6}/5$
