A. 1
B. 2
C. 9
D. 3n
Answer:C
9n x 3n - 1 = 11. (243)n/5 x 32n + 1 =?
A. 1 B. 2 C. 9 D. 3n
Explanation: 243)(n/5) x 32n + 1/9n x 3n - 1 is the given expression.1/(32)n x 3n - 1 = (35)(n/5) x 32n + 1/(32)n x 3n,35 x (n/5) x 32n + 1 = 35 x (n/5) x 32n + 1 = 35 x (n/5) x 32n (32n x 3n - 1),3(n + 2n + 1)/3(2n + n - 1) = 3(n + 2n + 1)= 33n + 1 = 33n - 1 = 33n - 1= 3(3n - 1 - 3n - 1) = 32 = 9.
