i know it's converge to 0, but I have trouble dealing with the n expontial, can someone tell me the general methof for finding the limits for $\displaystyle a^n/(b^n + 1)$
thanks, i have got another one, $\displaystyle n^2/\sqrt{2n^4+1}$
how do I deal with the squre root?
Divide the numerator and the denominator by $\displaystyle n^{2}$. When you bring the $\displaystyle n^{2} $ inside of the radical it becomes $\displaystyle n^{4} $

hmm, I dun quite understand it, can you show me the steps please?
