To simplify the expression \(100^8 \times 100^8\) using the Product Rule of Exponents, we use the rule that states \(a^m \times a^n = a^{m+n}\).
In this case:
\[ 100^8 \times 100^8 = 100^{8+8} = 100^{16} \]
Now, let's compare this to the options given:
- \(200^{15}\)
- \(100^{15}\)
- \(100^{56}\)
- \(10,000^{15}\)
None of these options is equivalent to \(100^{16}\). Therefore, it appears none of the provided options correctly represents the simplified form of \(100^8 \times 100^8\).
