# How do you write 2000000000000 in scientific notation?

Jun 17, 2018

$2.0 \times {10}^{12}$

#### Explanation:

Write as $2000000000000.0$
$\textcolor{w h i t e}{\text{dddddddddddddddd.d}} \uparrow$
color(white)("dddddddddd")"my added decimal point"

The objective in this case is to have:

$\textcolor{w h i t e}{\text{dddddd") 2."something decimals"xx10^("some number}}$
$\textcolor{w h i t e}{\text{dddddd}} \uparrow$
New decimal point position

If we count all the 0's between the 2 and to the decimal point I inserted, you have a count of $\textcolor{red}{\text{twelve 0's}}$

color(white)("d")ubrace(2."something decimals")xx10^(color(red)("some number"))
$\textcolor{w h i t e}{\text{ddddddd.d") 2.0color(white)("ddddddd.}} \times {10}^{\textcolor{red}{12}}$
