(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Sorry for the missing summation signs but could anyone help me investigate the convergance of the following infinte sum with n'th term equal to : (2n)!/(n^n)

2. Relevant equations

3. The attempt at a solution

I have tried ratio test and n'th root test but failed.

Im not even sure if it passes the vanishing test

would appreciate any ideas. Thanks
