# How do you rewrite 10,000,000 as a power of ten?

Mar 17, 2018

${10}^{7}$

#### Explanation:

We have: $10 , 000 , 000$

First, count the number of digits following the first digit (in this case its $1$):

$R i g h t a r r o w \text{Number of digits} = 7$

The way to express any large number in scientific notation is to multiply the first digit by $10$ raised to the power of the number of digits after the first one.

So $10 , 000 , 000$ would be expressed as $1 \times {10}^{7}$, or simply ${10}^{7}$.
