The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property. This number appears in the fractional expression for the golden ratio. It can be denoted … See more The square root of 5 can be expressed as the continued fraction $${\displaystyle [2;4,4,4,4,4,\ldots ]=2+{\cfrac {1}{4+{\cfrac {1}{4+{\cfrac {1}{4+{\cfrac {1}{4+{{} \atop \displaystyle \ddots }}}}}}}}}.}$$ (sequence … See more Geometrically, $${\displaystyle {\sqrt {5}}}$$ corresponds to the diagonal of a rectangle whose sides are of length 1 and 2, as is evident from the Pythagorean theorem. Such a rectangle can be obtained by halving a square, or by placing two equal squares … See more Hurwitz's theorem in Diophantine approximations states that every irrational number x can be approximated by infinitely many See more • Golden ratio • Square root • Square root of 2 • Square root of 3 See more The golden ratio φ is the arithmetic mean of 1 and $${\displaystyle {\sqrt {5}}}$$. The algebraic relationship between $${\displaystyle {\sqrt {5}}}$$, the golden ratio and the conjugate of the golden ratio (Φ = –1/φ = 1 − φ) is expressed in the following formulae: See more Like $${\displaystyle {\sqrt {2}}}$$ and $${\displaystyle {\sqrt {3}}}$$, the square root of 5 appears extensively in the formulae for exact trigonometric constants, including in the … See more The square root of 5 appears in various identities discovered by Srinivasa Ramanujan involving continued fractions.
