(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Integrate [tex]\int{\frac{lnx}{x^4}dx}[/tex]

2. Relevant equations

3. The attempt at a solution

I get this:

[tex]u = ln x, du = \frac{1}{x}[/tex]

[tex]dv=x^4, v=\frac{x^5}{5}dx[/tex]

[tex]\frac{(lnx)x^5}{5}-\int{\frac{x^5}{5}*\frac{1}{x}dx} = \frac{(lnx)x^5}{5}-\frac{6x^6}{5}dx}[/tex]

Am I doing this right?
