Question

How do you write 0.00050210 in scientific notation?

Answer 1

I tried this:

Explanation:

You need to write your number as a power of `10`; you need to move the decimal point to the right up to pass the first non-zero digit using the number of movements of the point as power:

`0.00050210`
`-->`
`5.0210xx10^(-"number of movements")`

giving: `5.021xx10^-4`
