Question

How do you write 0.005 in scientific notation?

Answer 1

`5*10^-3`

Explanation:

Scientific notation always starts with the first non-zero digit, then a decimal point.
Since the decimal was moved three places to the right (the negative direction), the exponent is `-3`.

Notice that `10^-3` equals `1/1000` or `0.001`

so multiplying 5 by either of these numbers equals `0.005`
