The population of a city is given as 3.45 * 10 ^ 6 A nearby city has a population of 1.3 * 10 ^ 5 What is the sum of t populations of the two cities in scientific notation? (1 point)

Answer 1

The sum of the populations of the two cities can be found by adding the numbers in front of the 10, and keeping the same power of 10.

(3.45 * 10^6) + (1.3 * 10^5)

To add the numbers in front of the 10, we can convert both numbers to the same power of 10.

3.45 * 10^6 = 34.5 * 10^5
1.3 * 10^5 = 13 * 10^5

Now we can add the numbers:

34.5 * 10^5 + 13 * 10^5

Adding the numbers in front of the 10 gives: 34.5 + 13 = 47.5

Keeping the same power of 10 (10^5) gives the final result as:

47.5 * 10^5

So, the sum of the populations of the two cities in scientific notation is 47.5 * 10^5.
