HEY MATE!!!

Question :- (9n+1)x(3-n/2)-2 - 27n / (3m x 2)3 =1/729

Answer :-

■ 32n+2 x 3n - 33n / 3m x 2m = 1/36

■ 33n+2 - 33n / 33m x 23 = 1/36

■ 33n (32 - 1) / 33m x 23 = 1/36

■ 3n (32 - 1) / 3m x 8 = 1/36

■ 3n x (9-1) / 3m x 8 = 1/36

■ 3n x 8 /3m x 8 = 1/36

■ 3n / 3m = 1/36

Therefore, m - n = 2

HOPE IT HELPS YOU!!!

Answer 2

Answer:

Answer :-

⇒ 32n+2 x 3n - 33n / 3m x 2m = 1/36

⇒ 33n+2 - 33n / 33m x 23 = 1/36

⇒ 33n (32 - 1) / 33m x 23 = 1/36

⇒ 3n (32 - 1) / 3m x 8 = 1/36

⇒ 3n x (9-1) / 3m x 8 = 1/36

⇒ 3n / 3m = 1/36

Therefore, m - n = 2

3n x 8 /3m x 8 = 1/36
