If `omega ` be a nth root of unity, then `1+omega+omega^2+…..+omega^(n-1)` is (a)0(B) 1 (C) -1 (D) 2

If omega ne 1 is a cube root of unity, then 1, omega, omega^(2)

if 1 , omega ,omega^2 ,............. omega^(n-1) are nth roots of unity , then (1-omega) (1-omega^2).......(1-omega^(n-1)) equal to

If 1, omega, omega^2 ,…..,omega^(n-1) are the nth roots of unity, then (2- omega)(2-omega^2)….(2-omega^(n-1) ) equals

If 1, omega,(omega)^2,.......omega^(n-1) are the nth roots of unity,then (2-omega)(2-(omega)^2)…...(2-(omega)^(n-1)) is equal to 2^n

if 1,omega,omega^(2),............omega^(n-1) are nth roots of unity,then (1-omega)(1-omega^(2))......(1-omega^(n-1)) equal to

If omega is the cube root of unity, then then value of (1 - omega) (1 - omega^(2))(1 - omega^(4))(1 - omega^(8)) is
