The problem asks to write the population estimate of 38,332,521 as a single-digit number times a power of 10.

To express this number in scientific notation or a similar form:
1. Round the number to one significant digit: 38,332,521 rounds to **4** (since 3 is closer to 4).
2. Count the number of digits after the first digit: there are 7 digits remaining.

Therefore, the population can be written as:
\[
4 \times 10^7
\]

This expresses the population as a single digit times a power of 10.
