## juanjohnguy Group Title Integral help! I'm just not seeing how to start to solve this integral.....its the integral of (ln(x+3))/(x+3) 2 years ago 2 years ago

1. freckles Group Title

did you try letting u=ln(x+3)

2. juanjohnguy Group Title

then what would make the (x+3) on the bottom?

3. freckles Group Title

$\int\limits_{}^{}\ln(x+3) \cdot \frac{1}{x+3} dx$ $u=\ln(x+3) => du=\frac{1}{x+3} dx$

Now just make those replacements and you will have something easy to integrate
