No takers? Oh well,

There are a couple of ways to do this.

The smart*** way would be that since

we have that

This can be shown by the limit

this was gotten from the fact that if

Therefore

The other answer that is better in my opinion would be the use of the ratio/root test trick

Now by termwise division with

we get

Good answer! The only thing is, that you did not show that all the other terms can be ignored via a limit as I did in mine (No big deal, I think we all know it to be true)...and did you just use L'hopital's?:D

If anyone sees a problem with any of my solutions let me know - June 9th 2008, 02:45 PMwingless
Well, my first answer is the same as yours, I just didn't show the details. And if you don't want to evaluate the limit using , use the L'hopital solution.. =)

EDIT:(sorry, I am making these up as we go) Tis is another easy one, if someone would like to post another one I would be more than happy to give up the posting position
