5. Find all three cube roots of the the complex number z = 473 + 4i, and plot
them in the complex plane.
Verify the identity

z1 = 7.71 + 0.02 i

z2 = 7.73 + 0.306 i

z3 = 7.78 + 0.59 i

Step-by-step explanation:

To find the roots you use:

    ( 1 )

n: the order of the roots

k: 0,1,2,...,n-1

First, you write z in polar notation:

Thus, by using these values for the angle and r in the expression (1), you obtain:

hence, from the previous results you obtain:

z1 = 7.71 + 0.02 i

z2 = 7.73 + 0.306 i

z3 = 7.78 + 0.59 i
