Muchidzidzo masvomhu, muchikamu chinodzidzidzisa muradanuro, hwaro inhamba b' inowanikwa patsazaniso inoti x = bn. Nhamba b iri kuradanurwa ne pawa n ndiyo inonzi hwaro. Zviri kuitwa pakuradanura nhamba b zvinogonga kunzwisiswa sezvizvi zvinotevera: b n = b × ⋯ × b ⏟ n , {\displaystyle b^{n}=\underbrace {b\times \cdots \times b} _{n},} Nhamba n inonzi muradanuri, iyi ndiyo nhamba inonongedza kana kutaridza kuti vana b vari kutsamana kangani. Kurerutsa Mutauro KuEnglish kunotaurwa zvichinzi nth power of b or b to the nth power. KuChishona zvakafanira kuti titi radanura b nepawa n kana kuti radanura b nemuradanuri n.
