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.)
