# Help with simple integral

Hi, I am sure this is simple stuff. I am stuck trying to solve this integral:

$$$e^{\int_{a}^{b} C\left(\frac{dlogH(x)}{dx}\right)^{1-\sigma}dx}$$$

I know I can get rid of the integral where there is a derivative and also get rid of the exponent with the log function - but not too sure what to do with the sigma?

Here is my attempt at a solution:

$$$=e^{C\int_{a}^{b}\left(\frac{dlogH(s)}{ds}\right)^{-\sigma}ds}\frac{H(a)}{H(b)}$]$$

Any help would be appreciated.

PS this is not a HW question:).
