What Is the Square Root Calculator?
A square root calculator finds the number that, when multiplied by itself, equals the given number. It also supports nth roots for when you need cube roots, fourth roots, and beyond.
The Formula
vx = y where y x y = x. For nth roots: nvx = y where yn = x.
Example
A square garden with an area of 225 square feet has side length sqrt(225) = 15 feet. A right triangle with legs of 3 and 4 units has a hypotenuse sqrt(9+16) = sqrt(25) = 5 units.
