To solve the given expression, we need to evaluate the powers of the numbers separately and then multiply the results. Specifically, calculate \(4^2\) and \(5^3\), and then multiply these two results together.
Step 1: Calculate \(4^2\)
First, we calculate the square of 4:
\[
4^2 = 16
\]
Step 2: Calculate \(5^3\)
Next, we calculate the cube of 5:
\[
5^3 = 125
\]
Step 3: Multiply the Results
Finally, we multiply the results from the previous steps:
\[
16 \times 125 = 2000
\]
