A) 729
B) 246
C) 243
D) 81
Correct Answer: A
Solution :
\[{{(1-2\omega +{{\omega }^{2}})}^{6}}\] = \[{{(1+{{\omega }^{2}}-2\omega )}^{6}}\] = \[{{(-\omega -2\omega )}^{6}}={{(-3\omega )}^{6}}\] \[={{(-3)}^{6}}{{({{\omega }^{3}})}^{2}}\] [Since \[1+\omega +{{\omega }^{2}}=0,\,{{\omega }^{3}}=1\]] = 729.You need to login to perform this action.
