limits - Result of limntoinftyfracx100nn!



The task is to lim. n is an integer. I've tried to use Stolz theorem, but that doesn't seem to give any result.



Thank you for your help.



Answer



By ratio test



\frac{{x}^{100(n+1)}}{(n+1)!}\frac{n!}{{x}^{100n}}=\frac{x^{100}}{n+1}\to 0



then



\lim_{n\to\infty} \frac{{x}^{100n}}{n!}=0
