Question

The points representing cube roots of unity (a) are collinear (b) lie on a circle of radius √3 (c) from an equilateral triangle (d) none of these

Answer 1

(c) from an equilateral triangle

Step-by-step explanation:

The cube roots of unity are given by

A(1,0) , B(-1/2,(rt3)/2, C (-1/2,- (rt3)/2)

The value for each of AB, BC and CA is rt3

Hence these points represent an equilateral triangle
