Question

How do you convert 0.0032 into scientific notation?

Answer 1

`3.2xx10^-3`

Explanation:

Move the point to the right and count the movements. Stop after the 3, eliminate the zeroes, take the remaining digits and include a power (negative->movement to the right) of ten corresponding to the number of movements:
`0.0032`
`0003.2` you made 3 moves:
`=3.2xx10^-3`

Answer 2

`3.2xx10^(-3)`

Explanation:

The premise of scientific notation is that you skip all those "extra zeroes" and go straight to the non-zero digits. However, that means that you do have to state how many zeroes you moved the decimal over.

The number `-3` means that I moved the decimal `3` places to the right, and that the number `0.0032` is smaller than the number `3.2` by `10^3`.
