Question

Can someone tell me why this is wrong? (Or rather, post your solution). I solved it and checked my answer with other sources, and it seems to be correct, but Web Assign is not accepting my answer. What seems to be the problem?

Answer 1

maybe write the denominator in terms of w and try again ?
because your answer is indeed correct.

Answer 2

if you observe, the denominator is w^3

Answer 3

oh, and by the way, you wrote "x" instead of u
first correct that and check

OH maybe it's the "x" .... let me check.
