22 question pls plsssssssss​

Answer 1

Step-by-step explanation:

9ⁿ × 3² × 3ⁿ = 3 ^( 2n) × 3^(n+2) = 3 ^ ( 3n+2)

Also, 27^(n) = 3^(3n)

the numerator is 3 ^ ( 3n+2) - 3^(3n)  = 3^(3n) × ( 3^2 - 1 ) = 8 × 3^(3n)

the denominator is 8 × 3^(3m)

8 will be cancelled and we get 3^(3n-3m) = 3^(-3)

so , 3n-3m = -3 and by solving it, we get m-n = 1
