Dear student,
The general term of the series can be given by:
T_{n}=\frac{n^{5}\left ( n+1 \right )^{7}}{n!}

So, the required sum can be found as:
S_{n}=\sum_{1}^{\infty}T_{n}=\sum_{1}^{\infty}\frac{n^{5}\left ( n+1 \right )^{7}}{n!}
Using the standard formulae, the required sum can be found.
Regards
Sumit
