Seems like you have two separate problems here.
A. sqrt%287%29+%2F+7%5E%281%2F5%29
rewrite as fractional powers as
%287%29%5E%281%2F2%29+%2F+7%5E%281%2F5%29
since we are dividing like bases, subtract exponents to get
7%5E%281%2F2-1%2F5%29
and then
7%5E%283%2F10%29
B. 80%5E%281%2F4%29+%2F+9
rewrite 16*5 to get
%28%2816%5E%281%2F4%29%2A5%5E%281%2F4%29%29+%2F+9%29
and then
%282%2F9%29%2A5%5E%281%2F4%29
