Answer:
A. 27x^6y^9 / z^9
Explanation:
Since the entire expressions is being raised to the third power, we raise each term inside the parentheses to the third power.
Note that when you raise an exponent to a positive exponent, you multiply the exponents according to the power of a power rule of exponents.
Now, we can start simplifying:
(3x^2y^3 / z^3)^3
3^3 * x^(2 * 3) * y^(3 * 3) / z^(3 * 3)
27x^6y^9 / z^9
Thus, the answer is A.
