Question

The mass of a typical raindrop is 8.7 x 10^-5 grams. What is 8.7 x 10^-5 in standard form?

Answer 1

Hello There!

$8.7 * 10^{-5}$ is in standard index form.
Standard form is when it is the original number
The '-5' as a power means you need to shift the zero back 5 spaces.
Or, divide by 100,000.
If you do this, you would get 0.000087.

Thus, making it option B.

Hope This Helps You!
Good Luck :)
