    The answer would end up being B. Because, you would actually divide the numbers and just subtract the exponents. You would only subtract the exponents when you're dividing though. But when you're say, multiplying, you'd add the exponents. Make sense?

    I believe it is D, but I'm honestly not 100% on that one.
