ABSTRACT
Suppose we have a real, positive number, N, and we wish to have the value of its square-root, denoted by https://www.w3.org/1998/Math/MathML"> N https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003178972/2df7c31e-87d5-4311-9568-69acef9e9d55/content/math1_3.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> , of course there are two values associated with this quantity, one positive, the second negative. However, our focus will only be on the positive square-root since the negative one differs only by a sign.
