To solve \(10^2 \cdot 10^3\), we can use the property of exponents that states \(a^m \cdot a^n = a^{m+n}\).
Applying this property:
\[ 10^2 \cdot 10^3 = 10^{2+3} = 10^5 \]
Now, \(10^5\) can be calculated as:
\[ 10^5 = 100,000 \]
So, the numerical equivalent of \(10^2 \cdot 10^3\) is \(100,000\).
The correct answer is:
100,000
