D.)3.77x10^7

Answer 1

Given:

Consider the population of California =
`3.9* 10^7`

Consider the population of Maine =
`1.3* 10^6`

To find:

The difference between the population of California and Maine.

Solution:

We have,

Population of California =
`3.9* 10^7`

Population of Maine =
`1.3* 10^6`

Difference between the population of California and Maine is

`\text{Difference}=3.9* 10^7-1.3* 10^6`

`\text{Difference}=3.9* 10^7-(0.13* 10)* 10^6`

`\text{Difference}=3.9* 10^7-0.13* 10^7`

`\text{Difference}=(3.9-0.13)* 10^7`

`\text{Difference}=3.77* 10^7`

Therefore, the correct option is D.
