# Integrate $\int_{0}^{\infty}\frac{x^a\ln(x)}{(x+b)}dx$ by the method of residues

How to evaluate $$\int_{0}^{\infty}\frac{x^a\ln(x)}{(x+b)}dx$$ where $b > 0$ and $-1 < a < 0$ using the method of residues, but I have done only problems of simple poles, but this is much more than that. I am stuck on this problem, any help will be greatly appreciated.
