Which of the following correctly used the Product Rule of Exponents to simplify the expression 100% • 100?

200^15
• 10, 000^15
100^15
100^56

The correct answer is 100^15.

The Product Rule of Exponents states that when you multiply two numbers with the same base, you add their exponents. In this case, the base is 100 and the exponents are 1 and 1. Therefore, 100% • 100 simplifies to 100^2, which is equal to 100^15.
