Homework Statement


Determine the convergence or divergence of the series. If the series is convergent, find its sum. Justify each answer.

(n=1, to infinity) \sum(7/9 + n^5)

Help please? I missed a lot of school recently from being sick and need help with this!

For clarification, do you mean

\sum_{n=1}^{\infty}\frac{7}{9 + n^5}

or do you mean

\sum_{n=1}^{\infty}(\frac{7}{9} + n^5)
 
Try adding up the first few terms. What do you get?

sorry I meant:

Thanks for the clarification. Alright, what have you tried so far?
 
jgens wants you think think about a comparison test, I'm very sure.
