- Number 2 is the one with $ \log_a2 $ and you have to find $ \lim_{a\to\inf}\log_a2 $ and other limits as a approaches different values.
Remember the change of base formula. Then this problem is a cinch.
$ \log_ab=\frac{\log_cb}{\log_ca}=\frac{\ln{b}}{\ln{a}} $
Once you convert the format over to a fraction of natural logs, the problem is much easier.
