(100x^3y^-2)/(64x^7y^4)

  • Algebra -

    Please simplify completely :)

  • Algebra -

    100/64 = 25/16

    x^3 / x^7 = 1/x^4

    y^-2 / y^4 = 1/y^6

    so (100x^3y^-2)/(64x^7y^4)
    =25/(16 x^4 y^6)

    wait isn't (y^-2)/(y^4)=y^2?

  • Algebra -

    nope

    (y^-2) times y^4 would be y^2, but you were dividing, so you have to subtract the exponents
    -2 - 4 = -6

    Ohh right thank you
