Methods of computing square roots - Wikipedia
Rational approximations of square roots may be calculated using continued fraction expansions. The method employed depends on the needed accuracy, and the available tools and computational power.
Approximation of Square Roots | Brilliant Math & Science Wiki
Here is a guide to find square root or rather their approximates. Let n n be the number whose square root we need to calculate. Let n n can be written as p+q p+ q where p p the largest perfect square less than n n and q q be any positive real number. Then, \sqrt {n} = \sqrt {p+q} ≈ \sqrt {p} + \frac {q} {2\sqrt {p}+1} n = p+ q ≈ p + 2 p+1q.

Estimating Square Root - Examples, Method, Values
Jul 30, 2024 · Here’s a basic guide on how to estimate square roots using a simple numerical approach: Identify the Nearest Perfect Squares: Locate the two perfect squares between which your number falls. For instance, if you are estimating the square root of 20, recognize that 16 (4²) and 25 (5²) are the nearest perfect squares.
Approximating Square Roots: A. Square roots are a common approximation problem and can be somewhat challenging since some educated guessing is involved. B. The good thing about square roots is we can often get the answer in a somewhat close range. This method is very similar to finding the exact value of a square root. 1.
