It seems that the population of the nearby city was not specified in your question. However, I can demonstrate how to add two populations in scientific notation if you provide the population numbers.
For example, if the population of the first city is \(3.5 \times 10^5\) (350,000) and the population of the nearby city is \(4.2 \times 10^4\) (42,000), you would add them as follows:
1. Convert both populations to the same power of ten if necessary:
- \(4.2 \times 10^4\) can be converted to \(0.42 \times 10^5\).
2. Now add the two populations:
\[
3.5 \times 10^5 + 0.42 \times 10^5 = (3.5 + 0.42) \times 10^5 = 3.92 \times 10^5.
\]
If you provide the specific populations, I can help you find the correct sum.
