If \(\left(\frac{3}{2}+i \frac{\sqrt{3}}{2}\right)^{50}=3^{25}(x+i y)\) where \(x\) and \(y\)
are real, then the ordered pair \((x, y)\) is
- A (-3,0)
- B (0,3)
- C (0,-3)
- D \(\left(\frac{1}{2}, \frac{\sqrt{3}}{2}\right)\)
Answer & Solution
Correct Answer
(D) \(\left(\frac{1}{2}, \frac{\sqrt{3}}{2}\right)\)
Step-by-step Solution
Detailed explanation
Let \(z=\frac{3}{2}+i \frac{\sqrt{3}}{2}\) \(\therefore\) \(r=\sqrt{\frac{9}{4}+\frac{3}{4}}=\sqrt{\frac{12}{4}}=\sqrt{3}\)…
