    The (12^1/2) is just a constant, and so you don't differentiate it (like above)....you just keep it like it is, and differentiate the (x^1/2), which you have done correctly

    OH NO
    root(3) / root(root(3)) = root(root(3))
    how?

    surely if you convert it into powers it =
    3^1/2 divided by (3^1/2)^1/2
    = 3^1/2 " 3^1/4
    = 3^1/4
    = fourth root of 3

    or is that the same?

    root(root(3)) === 4th root of 3
