The population of the first city is 3.45×10^6 and the population of the second city is 1.3×10^5.
To find the sum, we need to add the two population values together.
First, we must ensure that both numbers have the same power of 10.
We can rewrite 1.3×10^5 as 0.13×10^6.
Now, we can add the two populations:
(3.45×10^6) + (0.13×10^6) = 3.58×10^6
Therefore, the sum of the populations of the two cities is 3.58×10^6.
