    Find all the complex cube roots of w= 8(cos 150 + i sin 150). Write the roots in polar form with theta in degrees.

    answers look like;
    z sub 0 = ? (cos ?degrees + i sin ?degrees)
    z sub 1 = ? ( cos ?degrees + i sin ?degrees)
    z sub 2 + ? ( cos ?degrees + i sin ?degrees)

    First build the expression for x sub k with r=8, theta=150, and n=
