Step-by-step explanation:

Explanation:-

Step(i):-

Given    

we know that  cos π = -1

                        sin π = 0

now given data

we can write  

step(ii):-

In complex numbers nth roots of a complex number

Z = r(cosθ+i sinθ)

Step(iii):-

   now      

By using trigonometric  

Final -
