Thank you very much! That helped a lot, I just finished my proof. :D That makes sense why you'd have to break it up. I didn't put the relationship between \sum^{n}_{i=1}i = \frac{n(n+1)}{2} and (\sum^{n}_{i=1}i)^2 = \frac{n^2(n+1)^2}{4} together. lol

Hello, I am having trouble solving this problem. Maybe I'm just overreacting to it. In my two semesters in discrete math/combinatorics, I've never seen a problem like this (with two summations) and been asked to prove it. Can some one help? [SIZE="4"]\sum^{n}_{i=1} i^3 = \frac{n^2(n+1)^2}{4}...
