So, 1764 = 2² * 3² * 7²
and √(1764) = 2 * 3 * 7 = 42
Case b) Given number is not a perfect square
Let’s try N = 1771. We want x = √N.
1. Guess the nearest ‘round’ square, and take it as a first approximation of x.
40² = 1 600, so x = 40
2. Divide N by x : 1771/40 = 44,275
3. Take the average of 40 and 44,275 rounded to the nearest integer:
(40 + 44)/2 = 42, so now x = 42.
