यदि \((\sqrt{3}+ i )^{100}=2^{99}( p + iq )\), है, तो \(p\) तथा \(q\) किस समीकरण के मूल है -

  1. A \(x^{2}-(\sqrt{3}-1) x-\sqrt{3}=0\)
  2. B \(x^{2}+(\sqrt{3}+1) x+\sqrt{3}=0\)
  3. C \(x^{2}+(\sqrt{3}-1) x-\sqrt{3}=0\)
  4. D \(x^{2}-(\sqrt{3}+1) x+\sqrt{3}=0\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(x^{2}-(\sqrt{3}-1) x-\sqrt{3}=0\)

Step-by-step Solution

Detailed explanation

\(\left(2 e^{\mathrm{i} \pi / 6}\right)^{100}=2^{99}(\mathrm{p}+\mathrm{i} \mathrm{q})\) \(2^{100}\left(\cos \frac{50 \pi}{3}+\mathrm{i} \sin \frac{50 \pi}{3}\right)=2^{99}(\mathrm{p}+\mathrm{i} \mathrm{q})\)…
