Answer Posted / karthik

the value of x=4;
start from the innermost sqrt
1.sqrt(4)=2;
2.sqrt(4+2)=sqrt(6)=2// since ans is (2 root 3)it will
consider only 2 and left root 3
3.sqrt(4+2)=sqrt(6)=2

in the last root (sqrt(4+2))= ans is 2 root(3) just elimnate
root(3)

thus the remaining ans is 2

there fore X=4////
