The given expression simplifies to $3$.

Would you like further details on the simplification process, or do you have any other questions?

Here are five related questions for further practice:

1. How can we factor expressions involving powers of 3?
2. What would happen if the base in the given expression were 2 instead of 3?
3. How does the exponent rule $a^m / a^n = a^{m-n}$ apply in this case?
4. Can you generalize this type of simplification for any base, not just 3?
5. What is the result if you evaluate the expression for a specific $n$, like $n = 2$?

Tip: When simplifying exponential expressions, always look for common factors in both the numerator and denominator to reduce the expression more easily.
