Given that, ( 9^n x 3^2 x (3^-n/2)^-2 - 27^n) /( 3^3m x 2^3) = 1/27 
⇒ (3^2n x 3^2 x { 3^-(-2n/2) } - 3^3n )/ 3^3m x 2^3 = 1/(3^3) 
⇒ (3^2n x 3^2 x {3^n} - 3^3n )/ 3^3m x 2^3 = 3^(-3) 
⇒ ( 3^3n x 3^2 - 3^3n )/ 3^3m x 2^3 = 3^(-3) 
⇒ 3^3n[ 3^2 - 1] / 3^3m x 2^3 = 3^(-3) 
⇒ 3^3n[ 9 - 1 ] /3^3m x 8 = 3^(-3) 
⇒ 3^3n x 8 /3^3m x 8 = 3^(-3) 
⇒ 3^(3n-3m) = 3^(-3) 
comparing powers on both side, we get 
3n - 3m = -3 
⇒ 3(n-m) = -3 
⇒ (n-m) = -1 
or m-n = 1
