$3 \textcolor{red}{, 675 , 000 , 000.} = 3.675 \times {10}^{\textcolor{red}{9}}$

#### Explanation:

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

It is written in the form:

$n \times {10}^{x}$ where $1 \le n < 10$ 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.

$3 \textcolor{red}{, 675 , 000 , 000.} = 3.675 \times {10}^{\textcolor{red}{9}}$

(The decimal point was moved $\textcolor{red}{9}$ places to the left.)
