A) \[1\]
B) \[-1\]
C) \[i\]
D) \[-i\]
Correct Answer: B
Solution :
Given,\[x=\frac{\sqrt{3}+i}{2}\] \[\Rightarrow \] \[x=-{{\omega }^{2}}\] \[\left( \because \,\,{{\omega }^{2}}=\frac{-\sqrt{3}-i}{2} \right)\] \[\Rightarrow \] \[{{x}^{3}}={{(-1)}^{3}}{{({{\omega }^{2}})}^{3}}\] \[\Rightarrow \] \[{{x}^{3}}=-1\]You need to login to perform this action.
