$\displaystyle \int x^4 lnx$

So I used integration by parts

$\displaystyle u=lnx \ du= \frac1x \ dv= x^4 \ v=\frac15 x^5$

so using the formula

$\displaystyle UV-\int VdU$

I get

$\displaystyle lnx \frac15 x^5 - \frac15 \int \frac{x^5}x$

Here is where I get stuck, I am not sure how i should approach the integration. If I had the reciprocal it would be no problem.

$\displaystyle \int \frac{x^5}x$

any help is appreciated, thanks!
