Does the integral of x(ln x)^4 =
x^2/x(ln x)^4 - x^2(ln x)^3 + 3/2 x^2 (ln x)^2 - 3/2 x^2(ln x) + 3/2 x +C ?

Or did I do something completely wrong?
Sorry I didn't show my work, it would probably take me 30 mins to type it up here.

Why don't you try differentiating it and see? That's all we could do anyway, and we won't do your tedious work for you.

Maple gives

1/2*x^2*ln(x)^4-x^2*ln(x)^3+3/2*x^2*ln(x)^2-3/2*x^2*ln(x)+3/4*x^2+C

and, in the future, try www.integrals.com (which in this case does not give the form of the answer your looking for.)

LOL, i forgot about differentiating that. Damn, i was so tired after solving that my mind shut down. LOL THanks.

Thanks benorin too, my professor was telling us about some website that does that, and i forgot to write it down.
