Question Analysis
This question tests the understanding of the same base method by requiring the student to solve for in an equation where the exponents are multiples.

Key Concept Explanation
The key concept is that if the bases are the same, the exponents must be equal. In this case, the exponent on the left side is a multiple of the variable.

Step-by-step Solution
1. Given the equation .
2. Since the bases are the same, set the exponents equal:
