35: You should get
This is an indeterminate product. Apply the standard procedure: Change it into a ratio (by putting n "under") to prepare it for the l'Hospital rule.
Note that a smart thing would be to move the root out, because it does not cause any troubles.
Instead of n there is n2, but it is just a small change (powers are "nice") and definitely worth getting rid of the square root, which is usually a source of complications in calculations. The limit inside the square root is solved similarly to the one above and it is in fact easier, so here we will follow the more complicated way to help you along, should you try it. If you decide to go the easier way, these hints will become an approximate guide.
