The expression that is correctly developed to use the Product Rule of Exponents is:
10 superscript 8 baseline times 10 superscript 8 baseline (10^8 × 10^8)
This can be simplified using the Product Rule, which states that when multiplying two expressions with the same base, you can add the exponents. In this case:
\(10^8 \times 10^8 = 10^{8+8} = 10^{16}\)
