I need to integrate left side of this equation
$$r \left( \left(B \, \mathrm{ln}\dfrac{r}{R_2} +D \right) ^ \dfrac{-a}{a+1} + \left(F \, \mathrm{ln}\dfrac{r}{R_2} +D \right) ^ \dfrac{-a+1}{a+1}\right)\mathrm{d}r = ...$$
Where contants are $B, D, R_2, a, F$. Is it possible to express on some way these parts with exponents? In order to integrate it is necessary to first do this, then to integrate.
Or do I need to integrate numerical?
