The question is not in INDETERMINATE FORM.
you need to convert it in that form by using a simple formula...

:-  lim x->a   [ 1 + f(x)]^g(x)  =   e^lim x->a  f(x).g(x)

apply this formula and you get the ans as e^1/2 in the first one.

for the second put m=1/n 
hence when m->infinity.... n->0
and then apply the same formula
you get the ans as 1.
