Question:

The value of $\sqrt{6 + \sqrt{6 + \sqrt{6 + \cdots}}}$ is: / $\sqrt{6 + \sqrt{6 + \sqrt{6 + \cdots}}}$ का मान है:

1.
3 / 3
2.
2.5 / 2.5
3.
6 / 6
4.
2 / 2

Correct Answer: 3 / 3

Let the value be x. Then $x = \sqrt{6 + x}$, so $x^2 - x - 6 = 0$, giving (x - 3)(x + 2) = 0. The positive root is x = 3. / माना मान x है। तब $x = \sqrt{6 + x}$, अतः $x^2 - x - 6 = 0$, जिससे (x - 3)(x + 2) = 0। धनात्मक मूल x = 3 है।
