Add 5 to both sides

y + 5 = x^2

Take the square root of both sides

±√y + 5 = x

Switch sides

0=(x-2)(x+6)

x-2=0
x=2

x+6=0
x=-6

The mass of a typical raindrop is 8.7 x 10^-5 grams. What is 8.7 x 10^-5 in standard form?
eimsori [14]
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 :)
