`(2-omega)(2-omega^2) = 7`

If,omega,omega'2be the imaginary cube roots of unity,then prove that (2-omega)(2-omega^(2))(2-omega^(10))(2-omega^(11))=49

if 1,omega, omega^2 are the cube roots of unity then the value of (2-omega)(2-omega^2)(2-omega^(10))(2-omega^(11))=

1,omega,omega^(2) are the cube roots of unity then (2-omega)(2-omega^(2))(2-omega^(13))(2-omega^(17))

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

The value of the expression 1.(2-omega).(2-omega^2)+2.(3-omega)(3-omega^2)+.+(n-1)(n-omega)(n-omega^2), where omega is an imaginary cube root of unity, is………

(2-omega+omega^(2))^(2)
