The power rule of exponents states that when you raise a number to a power, and then raise that result to another power, you can simplify by multiplying the exponents.
So, if we apply the power rule of exponents to the expression 7^15:
7^15 = (7^3)^5
An expanded equivalent expression would then be:
(7 × 7 × 7)^5 = 343^5
If the expression 7^15 what is simplified using the power rule of exponents which of the following would be an expanded equivalent expression?
