Question: Why Maple can not solve this integral?!

Hi friends
This is strange for me, but Maple could not solve the below integral. I tried with online version
of Mathematica and it solved for me. The solution is Hypergeometry function. 
> f := ((1/2)*r+1/r)^(1/n);

> int(f, r);
What is the problem?
 
Regards!
