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 the populations of the two cities in scientific notation? (1 point)

Question

O 4.75 * 10 ^ 11

35.8 + 10 ^ 5

O 3.58 * 10 ^ 6

4.75 * 10 ^ 5

Answer 1

To find the sum of the populations of the two cities in scientific notation, we add the two numbers together.

3.45 * 10^6 + 1.3 * 10^5 = 3.45 * 10^6 + 0.13 * 10^6 = 3.58 * 10^6

Therefore, the sum of the populations of the two cities in scientific notation is 3.58 * 10^6.

So the correct answer is option C: 3.58 * 10^6.
