X^X^X^X =2 so we can take it as y then y =2.Now restructing the question we can say that X^Y=2 i.e X^2=2 so X =root(2).

x= square root of 2. Let's x^x^X...to infinity = y. Then y=2. If we substitute all the powers above the base x as y, x^y=2. But from the above, y=2. Therefore, x^2=2 and so, the answer x=square root of 2.
