Calc 3 Test Help

I have a test tomorrow and got some quick questions on some problems. I don't really need them worked out I just need help starting them. Thanks

Determine whether the series is convergent or divergent.

seriesSum((5-2 sqrt(x))/x^3, n, 1, infinity)
* Do I use p-series here and do I do limit comparison test?

seriesSum(1/(n ln(n)^2), n, 2, infinity)
* same question as above with p-series.

seriesSum((n+2)/(n+1)^3, n, 3, infinity)
*same as above also.

seriesSum((n+5)/root(n^7+n^2, 3), n, 1, infinity)
* p-series and how would I go about determining?...what can I use?

seriesSum(1/e^n+1/(n (n+1)), n, 1, infinity)
* I don't know where to start on this one. And find sum.

How do I get it to show the equation instead of just the wording? That would make it look a whole lot better.
