What is this calculator?
Calculate an integer nth root.
What can you use it for?
Use it when solving an exercise, checking a result, or working with the particular quantities shown in this form. Calculate an integer nth root.
How to use it
- Enter value.
- Enter root degree.
- Select Calculate (or Generate for random tools).
- Read the answer and any additional results below the form. Check the units and the limits of the method.
Formula and method
Nth root = sign(value) × |value|^(1/n)
The root degree must be a positive whole number. A negative value has a real root only when the degree is odd.
Worked example
Value: 27, Root degree: 3. The result is 3 (nth root).
Assumptions and limits
Inputs and outputs must stay within the supported finite number range. Displayed decimal answers may be rounded.
