Simplify the following expression, and rewrite it in an equivalent form with positive exponents. -15x^4y/17x^2y7

A. -3x^2/y^6 B.3x^2/y^6 C.-3x^6y^8 D. 52x^2/y^6

  • check for typos -

    there is not much you can do with -15/17

    put numerator and denominator in parentheses
    do you mean y^7 in denominator?

  • Math -

    i have to choose ab or c

    Well, Look at what you typed. No way anything with 15 in the numerator and 17 (a prime number) in the denominator is going to come out to a b c or d.
    You have a mistake or your book has a mistake.

    -51x^4y/17x^2y^7

    I think its A

    Thank you for the 51 instead of the 15
    Now you know the correct answer has to start with -51/17 which is -3
    x^4/x^2 = x^2
    so far
    -3 x^2
    now y/y^7 = 1/y^6
    so in the end
    -3 x^2 / y^6
    which is
    A
