Actually question which I found:

Find the sum of the series $1^1+2^2+3^3+ \cdots +n^n $

This question has been bothering me since a long time. Any help would be appreciated!

This is http://oeis.org/A001923 . Looks like there's no nice formula other than just doing it out. – Dan Uznanski Nov 07 '14 at 03:50

$\sum_{k=1}^nk^k~\approx~n^n$ – Lucian Nov 07 '14 at 04:11

Is there any proof that the formula doesn't exist? I tried searching the web for it, but couldn't find. – Harshal Gajjar Nov 07 '14 at 05:00
@Sil Yeah it does. Is it a good idea to delete this post? – Harshal Gajjar Dec 09 '19 at 11:58
