    y = 14 + root(3)(x) x = 14 + root(3)(x)

    and then I would cube both sides?

    did you mean to replace that one x with y?

    right isolate the cuberoot(y) part first by subtracting that other number on both sides then you can talk about cubing both sides

    x-14 = root(3)(y)

    (x-14)^3 = y
