# How do you write 0.000054 in scientific notation?

Mar 22, 2018

$5.4 \times {10}^{-} 5$

#### Explanation:

Scientific notation is a way to use rename really large, or really small numbers so that they are easier to use.

$0 \textcolor{red}{\text{."0000color(red)"5}} 4$
$\textcolor{w h i t e}{\text{x}} \implies$

We are going to move the decimal place to the right to remove all of the $0 ' s$. Put your finger at the decimal place and move it all the way until the 5. You should have moved $5$ spaces.

Put the decimal there and you should have:
$5.4$

Now since we moved $\text{5 spaces to the right}$ we are going to add a negative exponent to ten:
$5.4 \times {10}^{-} 5$
