Confirming a Summation Identity

  1. May 9, 2013 #1
    Hi all, I found this "identity" online on Wikipedia, and realized that it would actually come in pretty useful for me, if only I could prove that it is true. Can you guys help me on that?:
    $$\sum_{k=1}^nk^m=\frac{1}{m+1}\sum_{k=0}^{m}\binom{m+1}{k}B_k\;n^{m-k+1}$$
    where ##B_k## denotes the kth Bernoulli number.

    Looks like the proof is also on Wikipedia :)

    So the formula in my first post is correct?
