To find the sum of the populations of the two cities, we add the numbers in scientific notation:
3.45×10^6 + 1.3×10^5 = 3.45×10^6 + 0.13×10^6 (by converting 1.3×10^5 to scientific notation)
= 3.58×10^6 (by adding the numbers)
Therefore, the sum of the populations of the two cities is 3.58×10^6.
3.45×10^6 + 1.3×10^5 = 3.45×10^6 + 0.13×10^6 (by converting 1.3×10^5 to scientific notation)
= 3.58×10^6 (by adding the numbers)
Therefore, the sum of the populations of the two cities is 3.58×10^6.
