The set of real numbers x for which the series converges is?
How should this be approached?

Let
The above is not defined but we note that the first function goes towards 0 faster then the second function goes toward infinity. So I would say this would approach 0.
With this result we can use...
I think the above is valid...but i'm about 7 beers deep by now...soo dont trust me to much

It's no different then....
Which you most definately know, so I'm confused at why you are confused?
