Question

How do you write .00008935 in scientific notation?

Answer 1

`8.935 * 10^-5`

Explanation:

Write out the powers of ten until you get to the number of `0`'s you need. You can do this in your head after a while.

`1 = 10^0`
`.1 = 10^-1`
`.01 = 10^-2`
`.001 = 10^-3`
`.0001 = 10^-4`
`.00001 = 10^-5`

Now multiply a power of ten by a number between 1 and 10 to give you the number in the question.

`8.935 * .00001 = .00008935`
`therefore .00008935 = 8.935 * 10^-5`
