Square root of 2: Difference between revisions

The '''square root of 2''' (approximately 1.4142) is the [[positive [[real number]] that, when multiplied by itself or squared, equals the [[number 2]]. It may be written in mathematics as <math>\sqrt{2}</math> or <math>2^{1/2}</math>. It is an [[algebraic number]], and therefore not a [[transcendental number]]. Technically, it should be called the ''principal'' [[square root]] of 2, to distinguish it from the negative number with the same property.
