Question

simplify the following 3 ^ n into 9 ^ n + 1 by 3 ^ n -1 into 9 ^ n -1​

Answer 1

Step-by-step explanation:

3^n × (3²)^n+1 / 3^n-1 × (3²)^n-1

(3)^(n+2n+2) / 3^(n-1+2n-2)

3^(3n+2) / 3^(3n-3)

3^(3n+2-3n+3)

3^5 = 243

Answer 2

Answer:

3^n*9^n+1

3^n-1*9^n-1

=3^n

3^n-1

=3^n = 3^n+1

3^n-1 3^n+1

3^n(3^n+1)
