Kuboradiko

Kuboradiko en matematiko esas termino difinita por nombri reala e komplexa. Por nombro $x$ es tala nombro $y$, ke $y^{3}=x$. Rezulti di kubala radikifo havas simbolo ${\sqrt[{3}]{x}}$.

Grafikaji di funciono $y={\sqrt[{3}]{x}}$ – por omna reala nombro $x$ existas nur un nombro $y={\sqrt[{3}]{x}}$ esanta olua kubala radiko.
