To simplify the expression \( 1008 \cdot 1007 \) using the Product Rule of Exponents, we first express \( 1008 \) and \( 1007 \) in terms of their base \( 100 \):
- \( 1008 = 100^{8} \)
- \( 1007 = 100^{7} \)
Now using the Product Rule of Exponents, which states that when you multiply like bases you add the exponents:
\[ 100^{8} \cdot 100^{7} = 100^{8+7} = 100^{15} \]
Thus, the correct answer is:
10015 (100 superscript 15 baseline).
