Solvable with out approximation?

  1. Sep 8, 2004 #1
    Is there any way to tell in general if an integral in the form of [tex] \int x^n*e^{x^m} dx[/tex] where n and m are constants is solvable with out approximation?

    I can't offer you a blinding flash of insight, but if n=m-1, it should be solvable.

    In general, the answer is no for m>1 (except for n=km-1, for arbitrary positive integer k).
