Answer:
8x10^-7
Step-by-step explanation:
First one you have correct however the second one you were close lets figure it out:
0.0000008
In order to move the decimal in front of the eight we have to "jump" 7 times to the right. Furthermore since we have to move the decimal to the right our exponent will be negative. That means that we have:
![0.0000008=8 \times 10^{-7}](https://tex.z-dn.net/?f=0.0000008%3D8%20%5Ctimes%2010%5E%7B-7%7D)
