SUMMARY
The discussion centers on proving that 1, w, and w² are the three cube roots of unity, where w is defined as a primitive cube root of 1. It is established that the primitive roots form a multiplicative group of order 3, which is essential for understanding the properties of these roots. The solution involves demonstrating the relationships and identities that arise from the definition of w, specifically utilizing the equation w³ = 1.
