A) \[128\omega \]
B) \[-128\omega \]
C) \[128\,{{\omega }^{2}}\]
D) \[-128\,{{\omega }^{2}}\]
Correct Answer: D
Solution :
We have \[{{(1+\omega -{{\omega }^{2}})}^{7}}={{(-{{\omega }^{2}}-{{\omega }^{2}})}^{7}}\] \[={{(-2)}^{7}}{{({{\omega }^{2}})}^{7}}\] \[=128{{\omega }^{2}}\]You need to login to perform this action.
