**I need some help with an Integration. Here's the equation**

**I =**##\int_0^∞ \frac {x^{n+1}} {1 + x^n} ⋅ e^{-x^2/{2 \sigma^2}} ##

**I have tried to solve the equation by simplifying first like**

let, ## \frac x {\sqrt 2 \sigma} = v ##, so the ##x = v \sqrt 2 \sigma##

then, ##dx = \sqrt 2 \sigma d v##

Also, let ## {\sqrt 2 \sigma} = m, and \ 1+n = p##

**Finally, the integration is simplified as follows**

I = ##m^{p+1} \int_0^∞ \frac {e^{-v^2}⋅ v^p} {{1 + v^{p - 1} m^{p - 1}}} dv##

Now i don't know what to do from here!!!

Thank you in advance for your attention to to this post.

**I would appreciate any help.**
