Hello,

I have two problems with series first

so I will like to know of this is absolute convergent here for I use two test.

First and I think this is oké

then the second test but the dominator will be bigger then te nominator?

Or not?

Second problem

I will proof that this is convergent

if I calculated this then I get thus not convergent but it must be.

Who can help me out? Greets.
