Original Message (ID '462506') By jf:
The first thing to try is making the coefficients exact. int = Rationalize[1/Sqrt[0.75*z^(0.6) + 0.25*z^3 + 0.000082*z^4] ] Integrate[ int , z, Assumptions -> {Element[z, Reals]}] But that does not help here. You could maybe try re-writing the integrand as an order-20 polynomial in z^(1/5); I am not optimistic.
