HW #11

Hi!

I have trouble with #6 and # 9 on HW #11. Can someone help me?
For #6 are we allow to use p-series test? I try p-series and it converges.
On #9. I use L’Hopital’s Rule and I found out that it also converge. Does anyone know if we can actually use that rule? It wasn’t not the sheet though.

Hi. For #6 I used Integral Test and I got that it converges. For #9 I also used the Integral Test and I got that it diverges. I didn't get that #9 converged...

Yeah, I got the same answers as Maria. For both.

Did any of you do number 8 and/or 11? I really got lost on those problems.

Oh, and you can't use the P-series test for number 6 because it's not in the correct format, I think.
Like it's not just 1/n^(2/3).
For number nine, you can't use L'Hopital's Rule because if you do it, that's the Nth term test and that ends up equaling zero, which makes it inconclusive.

Just kidding, I totally got 8 and 11.
