    Algebra Help

    Yeah, I am having problems with these 3 problems.

    14. 6x^−2 y^−4 z
    15. (r ^−5 )(s^4 )
    16. (x^−3 y ^4 z^−2 ) (xy^2 z^−2 )

    The teacher is saying, Simplify each expression. Do not use negative exponents. So, what do I do with those negatives?

    Also, would it be against the rules to post the read of the questions That I have answered, so that somebody can check my work?

    It might help you to remember that

    x^{-1} = \frac{1}{x} .

    ooo yeah. So, anything that isnt declared that is a word is 1, so it would be 1\1, and that would be 1. Or soemthing like that.

    It would appear you have a perfect understanding of the situation.
