Evaluate :

`1/iota`` ( 1 + omega ) ( 1 + omega^2 ) ( 1 + omega^4 ) ( 1 + omega^8 )`

(1-omega) (1-omega ^ (2)) (1-omega ^ (4)) (1-omega ^ (5)) = 9

If omega is a complex cube roots of unity, then find the value of the (1+ omega)(1+ omega^(2))(1+ omega^(4)) (1+ omega^(8)) … to 2n factors.

find the value of (1+omega)(1+omega^(2))(1+omega^(3))(1+omega^(4))

If 1, omega, omega^2 be the three cube roots of 1, then show that: (1+omega)(1+omega^2)(1+omega^4)(1+omega^8)=1
