To simplify the expression \(1008 \cdot 1007\) using the Product Rule of Exponents, we recognize that when multiplying like bases, we add the exponents.
In this case:
\[ 1008 \cdot 1007 = 100^{8} \cdot 100^{7} \]
Using the Product Rule, we add the exponents:
\[ 100^{8} \cdot 100^{7} = 100^{8 + 7} = 100^{15} \]
So, the correct simplified expression is:
10015 (or \(100^{15}\)).
