D) - 32
Correct Answer: B
Solution :
\[{{(1-\omega +{{\omega }^{2}})}^{5}}+{{(1+\omega -{{\omega }^{2}})}^{5}}\] \[={{(-2\omega )}^{5}}+{{(-2{{\omega }^{2}})}^{5}}=-32{{\omega }^{3}}{{\omega }^{2}}-32{{({{\omega }^{3}})}^{3}}\omega \] \[=-32({{\omega }^{2}}+\omega )=-32(-1)=32\]You need to login to perform this action.
