$9$
When we raise a power to a power, we multiply the powers together and keep the base. Let's multiply the exponent of each term by the exponent outside of the parentheses: $(3^{(7)(2)})(3^{(-4)(3)})$ Multiply the exponents: $(3^{14})(3^{-12})$ We cannot leave the answer this way with negative exponents. When we multiply two numbers that have the same base but different exponents, we keep the base as-is and add the exponents: $3^{2}$ Evaluate the exponent: $9$
