Question

A=7 x 12^n •3^n+1 + 6 • 4^n+1 • 9^n+2 + 18^n+1 • 2^n+1

Answer 1

A = 7·2^2n ·3^(2n+1) + 2^(2n+3) ·3^(2n+5) + 2^(2n+2) ·3^(2n+2) =
= 2^(2n) ·3^(2n+1) ·[7+2³ ·3^4 +2² ·3] = 2^2n ·3^(2n+1) ·(7+648 +12) =
= 667·2^2n ·3^(2n+1)

Answer 2

A = 7·2^2n ·3^(2n+1) + 2^(2n+3) ·3^(2n+5) + 2^(2n+2) ·3^(2n+2)= 2^(2n) ·3^(2n+1) ·[7+2³ ·3^4 +2² ·3] = 2^2n ·3^(2n+1) ·(7+648 +12) =667·2^2n ·3^(2n+1) CRED...
