Answer 2

`3.158,697 *10^(6)` .

Explanation:

Given : In 2012, the total population of Florida was 3,158,697 people.

To find : What was the population in scientific notation,

Solution : We have given

3,158,697

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left

and to balance , multiply by
`10^(n-1)` .

We can see there are n = 7 in 3,158,697

So, we move decimal point 6 place to the left .

Then
`3.158,697 *10^(6)` .

Therefore,
`3.158,697 *10^(6)` .
