Starting from the raising power operator, defined between two numbers x and y over a number field, xy is not the same as yx, due to the missing commutativity property respect than the other sum and multiplication rank binary operators.
So this post is questioning for wich value of x in natural, integers, reals (or complex) number fields this identity is verified:
x2 = 2x .
This is what we call an equation to solve.
This problem could also be interpreted geometrically asking in which points the parabola y=x2 intersect the esponential function y=2x.
Before we start explo
