I need to integrate $ 0.095x^{-0.26}[1-(1+\frac{a}{x})^{-0.2}]$.

However, I am not sure how to multiply the exponents and then integrate it. Am I missing something easy?

Please make sure I did the LaTeX right. Is it $1+\frac{a}{x}$ or $\frac{1+a}{x}$? –  Javier Badia Sep 4 '13 at 18:23
    
the edit is correct –  Jackson Hart Sep 4 '13 at 18:26
    
by the way, my a = 2592000 –  Jackson Hart Sep 4 '13 at 18:52
    
Do I have to use the binomial theorem? –  Jackson Hart Sep 4 '13 at 18:58
    
The binomial theorem proper only works when the power is a positive integer. You could get a series expansion, but otherwise I doubt this has a closed form. If it was a definite integral, you may be able to relate to the beta function using the substitution $u=\frac{a}{x}$. –  Javier Badia Sep 4 '13 at 19:48
