    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
