First group the numbers under the root in pairs from right to left, leaving either one or two digits on the left (6 in this case). Try it: +2 × +2 = 4 and -2 × -2 = 4. Since a square root of a number must equal that number when multiplied by itself. When you multiply this number by itself, and set it up as a full equation (n * n = x), the two factors (n and n) are either both positive or both negative since they are the same number.

The square root of 2 is equal to the length of the hypotenuse of an isosceles right triangle with legs of length 1. Representations. Decimal, 7 mar sqrt=x**(1/2) is doing integer division. 1/2 == 0. So you're computing x(1/2) in the first instance, x(0) in the second. So it's not wrong. At the bottom of this page is how to find square roots by construction! Method 1 (with no dividing but it's slower). Suppose you want the square root of
