I think it’s right, sorry if I’m wrong...


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 in surd form as:

It is an irrational algebraic number.[1] The first sixty significant digits of its decimal expansion are:

which can be rounded down to 2.236 to within 99.99% accuracy. The approximation
