are all of these answers right?

No, only one of the answers is correct. The correct exponent that would make the two expressions equivalent is 8.

To correctly use the Power Rule of Exponents in the expression (10^9)^7, we need to raise the base (10^9) to the power of the exponent (7). The Power Rule states that when raising an exponent to another exponent, we need to multiply the exponents together.

Therefore, to find the correct answer, we need to multiply 9 (the exponent of the base) by 7 (the exponent of the entire expression).

10^9 * 7 = 10^63.

So, the correct response is: 10^63.
