To find the numerical equivalent of \(10^2 \cdot 10^3\), you can use the property of exponents which states that when you multiply two numbers with the same base, you add their exponents:
\[ 10^2 \cdot 10^3 = 10^{2+3} = 10^5 \]
Thus, the correct response is:
10 superscript 5 baseline (or \(10^5\)).
