Answer 2

n = 4

Explanation:

Properties of Exponents

We are required to solve the following equation:

`\displaystyle 7^7\cdot 7^5=((7^n)^4)/(7^4)`

Operating:

`\displaystyle 7^(7+5)=(7^(4n))/(7^4)`

`\displaystyle 7^(12)=7^(4n-4)`

Equating the exponents:

4n - 4 = 12

Adding 4:

4n = 16

Dividing by 4:

n = 4
