## Homework Statement

Find the indefinite integral:

[tex]\int{\frac{1}{x ln(x^3)}}dx[/tex]

**2. The attempt at a solution**

Well, since d/dx ln(x) is u'/u I know something is kinda wack with the bottom. I first tried to substitute with u=x^3, but then du is 3x^2 and there is only x on the bottom not x squared. I then thought it might be backwards, since the x on bottom is like x^-1 and it would have an integral with a natural log in it, but that wasn't really working out either.

I'm pretty stumped, I've attempted it several times.

Thanks for your help!
