Question

can u tell me d procedure for finding d squareroot of any no by hand in a simplified way

Answer 1

Here's a link to find square-roots by
1. guess and check, or
2. longhand, but exact extraction of square-roots.
Both apply to positive real numbers only.
If you expect to use a calculator (without the square-root function), you can use Newton's method.
