## Elementary and Intermediate Algebra: Concepts & Applications (6th Edition)

The answer is Option $(b)$.
RECALL: $(x^m)^n=x^{mn}$ Thus, raising a power to a power is equivalent to raising the same base to the product of the powers. Example: $(x^2)^3=x^{2\cdot3} = x^6$ Therefore, the answer is Option $(b)$.
