# Math Help - converge or diverge

1. ## converge or diverge

Can someone help me with this series,

[n^n] / [(n+1)^(n+1)]

which test should i use?

I've tried to n-th root test but that gives me 1, which is inconclusive, the ratio test, I can't cancel anything out, as for the other test, i dont think those can apply.

thanks

2. Try limit comparison test with 1\n, I think that should show that it diverges (just a hunch, no time to verify at the moment)
