<font size='4'><u>Square Root of any Number</u></font> <font size='3'>Find the nearest square root ( s ) below radicand ( r ) and apply to equation</font> {{{ sqrt( r ) }}} = {{{ s + (r - s^2) * (1/((s + 1)^2 - s^2)) }}} <br /> Example: {{{ sqrt( 54 ) }}} = 7 + ((54 - 49) * 1/(64 - 49)) = 7.333 <br /> Our Est Sqrt = 7.333 Actual Sqrt = 7.348 <br /> Will square root any number, including decimals, accuracy is within a few thousandths. It will NOT work for radicands below 4
