Question

How do you write `93,000,000` in scientific notation?

Answer 1

`9.3 xx 10^7`

Explanation:

The decimal point is to the right of the last zero, so move it to the left until you get in between the `9 and 3`, so that there is only one digit to the left.

That's `7` spaces, so your answer will be `9.3 xx 10^7.`

Scientific notation will always be written as
`" a number" xx 10` raised to a power.

The number will be between `1 and 10`

In case you ever have a scenario when your decimal moves the other way, the exponent then would be negative. For now your exponent is positive.
