# How do you convert 5.5 x 10^-3 into standard notation?

Jul 11, 2015

Remember that ${10}^{-} 3 = \frac{1}{10} ^ 3 = \frac{1}{1000}$

#### Explanation:

So you divide $\frac{5.5}{1000}$

But you can also move the decimal point 3 places to the left, and pad zeroes to fill the empty places:

In both casesthe answer will be $0.0055$

Easy to remember: you now have 3 zeroes at the left side of your number (including the one in front of the decimal point)
