If you dig deep you may find a perfect square hidden in the factors of a number. 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. Given an integer x find the square root of xIf x is not a perfect square then return floorx.

Group the pairs separately if the factors have any perfect square. Hereis the radical symbol used to represent the root. How to Solve Square Root Equation.
