The negative exponent denotes that your answer will be under one.With fractions as exponents, take the denominator to be the rootyou will take of the number and the numerator to be the actualpower after taking the root.
In this case the denominator is 2 so take the square root of 25.This is equal to 5. Then your numerator tells you to cube theresult so 5 cubed is equal to 5*5*5 which is 125. Now since theexponent was negative, just put that solution under 1 for a final answer of 1 / 125
