Someone can say that it is the root of the equation x^2-2=0. So, it is not a symbolic number. It is a constructible number. Okay, then, What is the value of sqrt(2) so that We can get 2.0 by squaring this value? I think both sqrt(2) and Pi have the same algebraic behavior. Any advice (without accepting the approximated value) regarding this issue can meet-up my thirst, and I’ll be grateful.
