# Evaluating $\int \limits_{a}^{\infty} \frac{\exp\left(-ax\right)}{\log(x)\left(c+x\right)^2}dx$

I have the following integral

$$\int \limits_{a}^{\infty} \frac{\exp\left(-ax\right)}{\log(x)\left(c+x\right)^2} dx$$

that I do not know how to evaluate. Could you please give me a hint?

Thanks in advance.

Is the denominator $(c+x)^2\log x$ or $\log[x(c+x)^2]$? –  Mercy Jul 27 '12 at 9:13
@Mercy: The TeX code (right-clicking the equation) gives the denominator as "\log{x}(c+x)^2". Although verification from OP would be nice... –  Nicolás Kim Aug 15 '12 at 17:59
The integral diverges for $a\le1$. –  Lucian Apr 10 at 5:13
