Question

How do you express `58,600,000` in scientific notation?

Answer 1

First, move the decimal point over until you have a number between 1 and 10.

`58 600 000.`
`5860000.0`
`586000.00`
`58600.000`
`5860.0000`
`586.00000`
`58.600000`
`5.8600000`

Stop! 5.86 is between 1 and 10. Now, count how many places you moved the decimal point.

The decimal point moved 7 places to the left. So, the final answer is:

`5.86 times 10^7`
