Square root of (50a^8/b^5) My answer is in the small box, and it has been marked as incorrect. Please help me figure out what I did wrong.

Your answer is correct. However whatever is telling you it is incorrect may not like the order in which you have written things in the numerator. If I were you I would try 5√2a^4 in the numerator.

√(50a^8 / b^5) = (5a^4/b^2)*√(2/b) or (5a^4 /b^3)*√(2b) for those who want no denominator under the radical

Assumes b is positive. Try (5a^4) sqrt(2) / |b|^5
