THE VALUE OF X SATISFYING EQUATION X=(2+(2-(2+X)1/2)1/2)1/2 ?
Dear rahul X=(2+(2-(2+X)1/2)1/2)1/2 x≥ 0 ................1 square x2 =(2+(2-(2+X)1/2)1/2) or x2 -2 =(2-(2+X)1/2)1/2 so x2 -2≥0 so x≥2 or x ≤-2 from equation 1 x≥2 and RHS 2-(2+X)1/2 ≥ 0 or x≤2 so only x=2 is possible Please feel free to post as many doubts on our discussion forum as you can.

Dear rahul
X=(2+(2-(2+X)1/2)1/2)1/2
x≥ 0 ................1
square
x2 =(2+(2-(2+X)1/2)1/2)
or
x2 -2 =(2-(2+X)1/2)1/2
so x2 -2≥0
so x≥2 or x ≤-2
from equation 1 x≥2
and RHS 2-(2+X)1/2 ≥ 0
or x≤2
so only x=2 is possible
