Question

In 2012, the total population of Florida was 3,158,697 people. What was the population in scientific notation, approximately?

3.2*10^5 A
3.2*10^6 B
3.2*10^7 C
32*10^7 D

Answer 1

it is approximately B

Answer 2

The correct answer would be,

3.2*10^6 B

When doing scientific notation it is important to note that you only want 2 numbers as the base of the scientifc notation. In this case it would 3.2.

Next, you must know how many places to move the decimal in order to gain the original number back (3,200,000). In this case you would move it 6 times to the right to regain the original number.

Hope this helps! Have a good day! c:
