if the expression 7^15 was simplified using the power rule of exponents which of the following would be an expanded expanded equivalent

Question

expression

Answer 1

The power rule of exponents states that (a^b)^c = a^(b*c).

Using this rule, we can simplify 7^15 as 7^(5*3).

Therefore, an expanded equivalent expression would be 7^5 * 7^3.
