Someone want to help meh out? I have two probs, I know some of you are math wizzes from reading the last math thread.

Anyways, problem:

Evaluate the integral. Solve by the simplest method--not all require integration by parts. (I don't know how to make the integral sign so you'll have to assume it's there.)

(x^4)(lnx)dx

and

1/x(lnx)^3 dx


First problem, toughest thing is, since I'm trying to make lnx my dv, I dunno how to integrate lnx. I looked this up and it said make lnx my u since it's easier to find the derivative for it (which it is) however, it never comes to a 0...

Suggestions please. You don't have to answer it for me, but any hints will work. Thanks much.
