The expression that is correctly developed to use the Product Rule of Exponents is:
10^8 × 10^8
This expression uses the Product Rule of Exponents, which states that when multiplying two expressions with the same base, you add the exponents:
\( a^m \times a^n = a^{m+n} \).
In this case, \( 10^8 \times 10^8 \) can be simplified to \( 10^{8+8} = 10^{16} \).
Other options do not correctly illustrate the Product Rule.
