I'm doing some review of series and using the ratio test for convergence.
I have the problem (the summation of) n!x^n/n^n
I remember the ratio of convergence = e but I forgot the trick to get to there. Would someone mind refreshing me?
Thanks!

for a series you have,
Ratio test will tell you that:
if X<1, the series is absolute convergent
if X>1, the series diverges
