$$ \int 5 \mathrm{ln}(x^{1/3}) dx$$
Working with natural log is very unfamiliar to me (I think I was cheated in my Calc 1 course). I know that integrating $\frac{1}{x} = \ln x$, but is it the same in reverse? Also would this simply be $u$ - substitution or instead integral by parts? 

Help is so very appreciated!
