The Product Rule of Exponents states that when multiplying two expressions with the same base, you can add the exponents. In your case, you have:
\[ 1008 \cdot 1007 = 100^{8} \cdot 100^{7} \]
Using the Product Rule:
\[ 100^{8} \cdot 100^{7} = 100^{8 + 7} = 100^{15} \]
Thus, the correct answer is:
\[ 100^{15} \]
So the correct response would be:
100¹⁵
