Get the square root of any number as a decimal, and — for whole numbers — in simplified radical form like 6√2.
Step by step
Enter a number to get its square root and simplified radical.
Type any non-negative number. Whole numbers also get a simplified radical; decimals get the decimal root only.
The principal (positive) square root is shown first, rounded for display.
For a whole number, the root is written as a coefficient times a smaller radical, like √72 = 6√2, by pulling out perfect-square factors.
