Muchidzidzo masvomhu, kutambanura (Exponentiation in English) chiitiko chinonyorwa sezvizvi, bn, chinotora nhamba mbiri, hwaro b ne mutambanuri (kana munongedzo) n. Kana n ari nhamba izere uye ari nhamba yakakura kudarika zero, kutambanura kwakafanana nokupamha kuwanza. Izvi zvinonyorwa sezvizvi: b n = b × ⋯ × b ⏟ n , {\displaystyle b^{n}=\underbrace {b\times \cdots \times b} _{n},} zvinoda kunofanana ne kuwanza kunova kunodzokorora kukumbanidza: b × n = b + ⋯ + b ⏟ n . {\displaystyle b\times n=\underbrace {b+\cdots +b} _{n}.} Kurerutsa Mutauro Zvakakosha kuti pave nekuturikirwa kwemazwi anoshandiswa kuEnglish kuti kutaura kureruke sezvizvi: 5th power of 10 tinenge toti pawa rechishanu ra gumi. 2 exponent 5 anenge onzi mbiri nomunongedzo shanu. b raised to the power n inoturikirwa ichinzi b achitambanurwa nepawa n. 10 to the third power inonzi gumi kupawa rechitatu. Mukutaura kwemazuva ose kutambanura zvinoreva kurebesa tambo nenzira yokubhedhenura kana kumononora - (uncoil). Shoko rokuti kutambanura (hold out hand; open out roll) rinoreva kutambanudza ruwoko kana kupetenura chinhu chakapetwa, izvi zvoita kuti hukuru hwacho huwonekwe.
