Finding a square root without a calculator can be done by guessing at the approximate "right" answer then adjusting the guess until the answer squared is close enough to 2 to meet your need. There is however a formal process (Described at Link) which gives the right answer to any degree of accuracy needed.

What is the square root of 20 in simplest form?
sqrt(20) = sqrt( 5 x 4) = sqrt(5 x 2 x 2) = sqr(5) X sqrt(2) x sqrt(2) NB The sqrt(2) X sqrt(2) = 2 Hence sqrt(5) X 2 Ususally written as 2sqrt(5) = sqrt(20) . NB It is written in this form ' 2sqrt(5) ' in order to indicate that the '2' is a coefficient of the sqrt(5) and NOT to be 'square rooted'.
