A) 0
B) 1
C) \[\omega \]
D) \[{{\omega }^{2}}\]
Correct Answer: A
Solution :
\[\Delta =\,({{\omega }^{3n}}-1)+{{\omega }^{n}}({{\omega }^{2n}}-{{\omega }^{2n}})+{{\omega }^{2n}}({{\omega }^{n}}-{{\omega }^{4n}})\] \[\Delta \,=(1-1)+0+{{\omega }^{2n}}[{{\omega }^{n}}-{{({{\omega }^{3}})}^{n}}{{\omega }^{n}}]\] \[\Delta =0+0+0=0\].You need to login to perform this action.
