[(-8x^6)/(y^-6)]^2/3

  • pre-cal -

    (-8 x^6 y^6)^2/3
    square everything to get rid of that pesky - sign
    (64 x^12 y^12 )^1/3
    now take the cube roots
    4 x^4 y^4

    Simplify and show work: [(X^(2)+3)^(1/3)](-1)(x^(-2))+[1/3(x^(2)+3)^(-2/3)](2x)(x^(-1)) My answer key says that it's this but I have no idea how to get to it. I've tried 4 times already and failed each: [-(x^(2)+9)]/[(3x^(2))(x^(2)+3))^(2/3)]
