Question

In September 2015, there were approximately 2 million people living in Cedar City. In September 2018, that population grew to 8 million people. How many more people lived in Cedar City in 2018? Write your answer in scientific notation.

Answer 1

6×
`10^(6)`

Explanation:

6,000,000.

You need to move the decimal point to where you have a number between 1 and less than 10 (like 9.99999)

6.0×10n

Now to find the value of the n, count how many places you need to move the decimal point in order to change it from 6,000,000. to 6.0. My count says 6 places. So the scientific notation version of 6 million is

6.0×10 6

you could also say

6×10 6

I hope this helps,
