Question

How do you write `4,730,000,000` in scientific notation?

Answer 1

`4.73*10^9`

Explanation:

`4.73*10^9`

Easy trick for scientific notation is to remember the first number (before the multiplication) has to be between 1 and 10, always. So you have `4 730 000 000` can't be `473.0` (too big), `47.3` (too big) but `4.73` fits right between 1 and 10, so that's good.

Then for the order of the 10 count how many leaps all the way to right from the decimal in this case there are 9 numbers after the decimal so it's to the ^9
