Can anyone explain to me how I solve 3x10^8 / 3.82x10^-7 I know the answer due to referring to the key but I'm not sure how they got it. Answer was 7.85x10^14

You have to do this on a calculator. So when you put it in the calculator you will get 7.85x10^14.

3x10^8 is the speed of light. 3.82x10^-7 is the number in the question.

You can solve it like this

3x10^8

3.82x10^7                  

But you would do this on a calculator.

b is the correct answer

mark me brainliest and hope this
