    Hi Gurparwaan,

    Firstly you are in the wrong forum. Try posting it in the algebra forum. And before you post it there show your attempt at the problem and where you find it difficult to solve.

    It is clear that x = \sqrt{2} + x has no solution

    Please state this problem more carefully. I suspect that you may mean something like x=√{2+√[2-√(2+x)]}, or x = \sqrt{2+\sqrt{2-\sqrt{2+x}}}. Even then, the problem does not make much sense unless the sign in the middle of that expression should be a +.
