Question

answer me i will mark brailiest ​

Answer 1

Answer:

9×3^n = 3^7

3^2×3^n = 3^7

     3^n = 3^7÷3^2

      3^n=3^(7-2)

      3^n=3^5

hence n = 5

Answer 2

Step-by-step explanation:

1. 9 × 3^n = 3⁷

3² × 3^n = 3⁷

3^2+n = 3⁷

hence, 2+n = 7

n = 7-2

n = 5

● Option 2 is correct.

2. (3²)⁵ ÷ 3⁴ = ?

3²×⁵ ÷ 3⁴

3¹⁰ ÷ 3⁴

3^10-4

3⁶

● Option 1 is correct

Hope this will help you.
