# Math Help - [SOLVED] Natural Logarithmic Integration

1. ## [SOLVED] Natural Logarithmic Integration

Integrate the following:

ln(x)^2/x dx
I get stuck when I do the u-subxtitution.

2. If it's $\ln x^2,$ then it's quite easy since $\ln x^2=2\ln x,$ so worry about by $\int\frac{\ln x}x\,dx.$

3. If indeed it is $\int\frac{(ln x)^2}{x}dx= \int(ln x)^2(dx/x)$, then use the substitution u= ln(x). Since du/dx= 1/x, du= dx/x and the integral becomes $\int u^2 du$.

4. thanks!!!
