Final answer:
The expression (82) simplifies to 80 using the power of a power rule.
Step-by-step explanation:
The expression (82) can be simplified using the power of a power rule. The correct application of this rule is option d. (812) - 812-3 = 80.
To simplify (82), you can calculate the individual powers first. 812 equals 64, and 812-3 equals 16. Then, subtract the second power from the first power to get the final answer, which is 80.
Therefore, the expression (82) simplifies to 80 using the power of a power rule.
