The square root of 3 is the positive real number that, when multiplied by itself, gives the number 3. It is denoted mathematically as ${\ extstyle {\\sqrt {3}}}$ or ${\\displaystyle 3^{1/2}}$ . It is more precisely called the principal square root of 3 to distinguish it from the negative number with the same property. The square root of 3 is an irrational number. It is also known as Theodorus' constant, after Theodorus of Cyrene, who proved its irrationality.
