Question #e91e7

Answer 1

`3color(red)(,675,000,000.) = 3.675 xx 10^color(red)(9)`

Explanation:

Scientific notation is a way of writing very big or very small numbers using powers of 10.

It is written in the form:

`n xx 10^x` where `1<=n<10` and `x` is an integer indicating the number of place holders to give a number of the correct size.

This means " There must only be ONE digit before the decimal point.

`3color(red)(,675,000,000.) = 3.675 xx 10^color(red)(9)`

(The decimal point was moved `color(red)(9)` places to the left.)
