Question

How do you write `0.024` in scientific notation?

Answer 1

`2.4 xx10^-2`

Explanation:

Write the number as a power of 10, with one digit(not 0) before the point. This is a small decimal, so the power is negative.
The point has to be moved two places to the right (divide)

`0color(red)(.02)4 = 2.4xx10^color(red)(-2)`
