If \(1, \omega, \omega^2\) are the cube roots of unity, then \((2-\omega)^2\left(2-\omega^2\right)^2\left(2-\omega^{10}\right)^2\left(2-\omega^{11}\right)^2=\)
- A \(-7^4\)
- B \(7^4\)
- C \(7^8\)
- D \(-7^8\)
Answer & Solution
Correct Answer
(B) \(7^4\)
Step-by-step Solution
Detailed explanation
\(1, \omega, \omega^2\) are the cube roots of units. \(\Rightarrow 1+\omega+\omega^2=0\) Given, \((2-\omega)^2\left(2-\omega^2\right)^2\left(2-\omega^{10}\right)^2\left(2-\omega^{11}\right)^2\)…
