What this calculator does
Extract perfect powers from a nonnegative integer radical.
How it works
The calculator evaluates ⁿ√N = a·ⁿ√b after extracting every perfect nth-power factor aⁿ. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
Input query strings and outputs
Use an input name in this page’s URL as ?name=value, and join additional inputs with &. Portable shared links may instead use the compact ?ac= state parameter.
