Triple Integral

    I need to prove the following:


    Or, as a generalization:


    ...if there is such a generalization.

    I don't know where to begin, any suggestions?

    Thanks a lot for your help.

    You can make a Taylor expansion of the denominator since it is convergent for every point in the domain of integration.

    Alright, a friend showed me how to do this for m=3. Does this work?


    and since [tex]\int_{0}^1x^kdx=\frac{1}{k+1}[/tex], the sum can be rewritten as follows:


    This works? Or, is the proof more in-depth? I would like to know whether the needs to be a justification for evaluating the outside sum first.

    Thanks again.
