nthroot
Computes the nth root as a principal fractional power.
nthroot(x,n) is represented as x^(1/n), so branch behavior follows Nerdamer's power rules. Use cbrt when the real cube root of a negative real is specifically required.
Examples
These examples use Nerdamer Notation.
Take a fourth root using the principal power.
nthroot(81,4)Keep a symbolic root degree.

Nerdamer Notation
Use this form inside input passed to nerdamer(...).
nthroot(arg1, arg2)nerdamer.nthroot
Call the operation through the default nerdamer import.
nerdamer.nthroot(x: ExpressionInput, n: ExpressionInput): ExpressionParameters
| Name | Type | Description |
|---|---|---|
x | ExpressionInput | The expression whose root is requested. |
n | ExpressionInput | The root degree. |
Returns
Expression — `x^(1/n)`.
