To find the sum of the populations of the two cities in scientific notation, we will add the populations together.
The population of the first city is given as 3.45 x 10^0.
The population of the second city is given as 1.3 x 10^5.
To add these populations together, we need to make sure the powers of 10 are the same. We can do this by converting the population of the first city to scientific notation:
3.45 x 10^0 = 3.45 x 10^5 x 10^-5
Now we can add the two populations together:
(3.45 x 10^5) + (1.3 x 10^5) = 4.75 x 10^5
Therefore, the sum of the populations of the two cities in scientific notation is 4.75 x 10^5.
The correct answer is:
• 4.75 × 10^5

The correct answer is:
• 4.75 × 10^5
