B) 8
C) 9
D) 27
E) 32
Correct Answer: E
Solution :
\[{{(1+\omega -{{\omega }^{2}})}^{5}}+{{(1-\omega +{{\omega }^{2}})}^{5}}\] \[={{(-{{\omega }^{2}}-{{\omega }^{2}})}^{5}}+{{(-\omega -\omega )}^{5}}\] \[=-32{{({{\omega }^{2}})}^{5}}+(-32){{\omega }^{5}}\] \[=-32(\omega +{{\omega }^{2}})=32\]You need to login to perform this action.
