If `omega` is the cube root of unity, then find the value of: `((-1 + isqrt(3)) / 2)^18 + ((-1 - isqrt(3)) / 2)^18`

If omega is a complex cube root of unity, then find the values of: (1 + omega^2)^3

If omega is a complex cube root of unity, then find the values of: omega + 1/omega

If omega is the complex cube of unity, find the value of (1+ omega^2)^3

Find the value of: omega^18

If omega is a complex cube root of unity, then find the values of: (1 - omega - omega^2)^3 + (1 - omega + omega^2)^3

Find the value of omega^18
