To find the numerical equivalent of \(10^2 \times 10^3\), we can use the property of exponents which states that when multiplying numbers with the same base, we add the exponents:
\[ 10^2 \times 10^3 = 10^{2 + 3} = 10^5 \]
Now calculating \(10^5\):
\[ 10^5 = 100,000 \]
So, the numerical equivalent of \(10^2 \times 10^3\) is \(100,000\).
