DSSSB TGT CS Mock 04 – Question 057

Question:

Find the value of \(\sqrt{6 + \sqrt{6 + \sqrt{6 + \dots \infty}}}\).
\(\sqrt{6 + \sqrt{6 + \sqrt{6 + \dots \infty}}}\) का मान ज्ञात कीजिए।

Options:

  • 3
  • 2
  • 6
  • 1
  • 3
  • 2
  • 6
  • 1

Correct Answer: a)

Explanation:

Let \(y = \sqrt{6 + y} \implies y^2 – y – 6 = 0 \implies (y – 3)(y + 2) = 0\).
Since \(y > 0\), \(y = 3\).
\(y^2 – y – 6 = 0\) को हल करने पर धनात्मक मान 3 प्राप्त होता है।
