    What do you do when you have two exponents with the same base being divided by each other?

    You subtract them correct?

    So, take the numerator's exponent and subtract with the denominator's exponent

    subtract it from the denominator's exponent

    its fine, I got -4/7 too but the math program doesn't like that answer, when I simplify I get -2/5 and it still says its wrong

    that should be the answer, is the problem copied down correctly? If so, then it's just the program and you might have to talk to your instructor. well, the basic idea is that when you have exponents with the same base being divided from each other you just subtract the exponents. Alternatively, when you have same base exponents being multiplied by each other, you just add the corresponding exponents. I hope that helps.
