Given
$$a_n=sqrtn^2+3n-n$$
how can I calculate
$$
lim_ntoinftya_n ?
$$
I tried rationalizing, but got nowhere.

A better way to post is to show how you did the rationalization and explain why you thought you could go nowhere. These things would make your post easy to be accepted and to receive more advices to help you.

$$a_n = sqrtn^2+3n-n = frac3nsqrtn^2+3n+n = frac3sqrt1+3n^-1+1 to frac3sqrt1+1 = frac32$$
