How to use this calculator
Calculate square roots with a decimal result and exact radical simplification for supported integers.
How the calculation works
- Enter a non-negative number.
- The calculator shows the decimal square root.
- For integer values, it also shows a simplified radical form and short steps.
Formula
sqrt(x) is the value that multiplied by itself equals x. Reducible radicals factor out the largest square factor.
Example
sqrt(72) = sqrt(36 x 2) = 6sqrt(2).
Understanding your result
Use the output as a practical starting point, then review it before using it in an important workflow.
Assumptions and limitations
- Complex-number roots are not included in V1.
- Exact radical steps are intended for non-negative integers.
