- The way to do this is as follows:
-
- Solve k2*p^n - k1 = 0. The solutions are (k1/k2)^(1/n) times the
- n'th roots of unity. This allows you to completely factor k1 - k2 * p^n
- into linear factors. Now decompose it into partial fractions and integrate
- term by term. A symbolic algebra package will help.
