# Math Help - Integration by parts

1. ## Integration by parts

Okay, I can handle this equation without the ln(x)^2 but, that's throwing me. I've tried looking at it both ways to figure out what would be better, but I'm not getting the right answer. Any help.

let $u = (\ln x)^2$ and $dv = x^4$. and do it again, letting $u = \ln x$ next time

3. Ahh, that's what I did wrong. I didn't do the second u be ln. Thanks.
