f(x)=9^x/(9^x+3) . Find the value of
f(2/57)+f(3/57)+f(4/57)+....+f(54/57)+f(55/57)
1)1
2)55/(57)^54
3)27
4)None of these
i dont see any clue to solve it .
I need
(1) how to attack this problem ?
(2)
can i use some brute force or rough method to choose the right answer from above without solving the problem completely ?
