integral (x^6)ln(x)dx

The thing is... I have the exam in 2 days and this is the main thing I am havin problems with!

I tried makin u=x^6

and then integratin by parts which didnt seem to work!

I ended up gettin (x^6)(lnx)-(6x^5)(lnx^2)

Is this completely wrong... do I continue to integrate... Is there another way to do this?
