Web9 apr. 2024 · In this question we are going to prove that the cube root of unity in L.H.S. is equal to the real number in the R.H.S., by using the values: If ω is the cube root of unity then, ω 3 = 1 , 1 + ω + ω 2 = 0 . Complete answer: In this problem, We are given that, ( 1 − w + w 2) 5 + ( 1 + w − w 2) 5 = 32 L.H.S, = ( 1 − w + w 2) 5 + ( 1 + w − w 2) 5 WebIf the cube root of unity are 1,ω,ω2 then the root of the equation (x−1)3−8=0.

So, product of cube roots of unity = 1 ∙ ω ∙ ω 2 = ω 3 = 1. Therefore, product of the three cube roots of unity is 1. Property IV: ω 3 = 1 We know that ω is a root of the equation z 3 - 1 = 0. Therefore, ω satisfies the equation z 3 - 1 = 0. Consequently, ω 3 - 1 = 0 or, ω = 1.
