Such a number is algebraic and can be expressed as the sum of a rational number and the square root of a rational number. Constructible number: A number representing a length that can be constructed using a compass and straightedge. Constructible numbers form a subfield of the field of algebraic numbers, and include the quadratic surds.

A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

Since √ 2 is a real number, which can be either rational or irrational, the only option left is for √ 2 to be irrational. [ 11 ] (Alternatively, this proves that if √ 2 were rational, no "smallest" representation as a fraction could exist, as any attempt to find a "smallest" representation p / q would imply that a smaller one existed ...
