Integration (by parts) question (1 Viewer)

Can someone help me find my error? (q47 of ex 33f from fitzpatrick). The first line of my solution isnt mathematically correct, i know. should read d/dx of (1/m+1)*x^m+1 not d/dx of x^m

Nevermind, I found it. I forgot the chain rule when differentiating (lnx)^n. Thanks for everyones help?
