If \(y=x^{x^{x}}\)

Make \(x\) as the subject of formula. ..

ie. \(x=f(y)\)?

Is it possible to do so ?

TopNewestI don't think it can x can be expressed by y in elemantary form, such as polynomials, trigonometry etc.In the case \(x^x=y\), the solutions for x need the Lambert W function, which is kinda weird, because it's just defined to be the solution to \(x.e^x=y\), and it cannot be expressed with elementary functions. Maybe someone who knows about it can make a note or something.In the case \(x^{x^x}\), I haven't the vaguest idea.

x will always remain one and it is independant of y

Because it is invertible, It might be possible.

I meant x=y root y

Can u explain?

the question is y=x to the power x and this continues till infity.Now if you remove 1 unit from infinity then also it remains infinity only.Hence you write y=x to the power y.

16= 2^2^2..

by ur method, we get 2=16^(1/16) 16=2^16.(in 2nd reply) ..which is incorrect
