Hi, im having difficulty in understanding the following concept. can someone help me with a step by step explaination please.

I can find the roots = z = -4, 2+2 sqrt 3i, 2 - 2 sqrt 3i. but then i cant understand the rest

Find all roots of the equation: z3+64=0. Present your answer in the exact form (don't use calculators).

• Show the roots in the Argand diagram.
• Find the midpoint in the first quadrant (if any) between two roots and show it in the Argand diagram. Present your answer in the exact form.
• Find the real and imaginary parts of each complex root in the exact form.
• Find the module and argument of each root.
• Present each root in the exponential form.
• Find the angle between each root.
