my try

left hand side can be minimized to

3^3m while the right will be 3^2*n (9 is 3^2)

therefore:

3m = 2n
m/n = 2/3

@ engin : please check ur math.. all u have to do is bring n to the left side and take 3 to the right side. u shld arrive @ the right answer...

@ siddarthd2919: the question is 3^m*3^m*3^m
now u shld get the answer.
