    multiple integral

    Has anyone seen an analytical solution to this integral:

    <br />
    " alt="\int_0^1\cdots\int_0^1\frac{1}{(x_1+\cdots+x_N)}dx _1\cdots dx_N
    " />

    I would be grateful for any help!

    Do you mean this \int_0^1\cdots\int_0^1\frac{1}{(x_1+\cdots+x_N)^N}  dx_1\cdots dx_N ??
