{{Main|Exponentiation}}
When multiplication is repeated, the resulting operation is known as ''[[exponentiation]]''. For instance, the product of three factors of two (2×2×2) is "two raised to the third power", and is denoted by 2<sup>3</sup>, a two with a [[superscript]] three. In this example, the number two is the ''base'', and three is the ''exponent''.<ref>{{Cite web|last=Weisstein|first=Eric W.|title=Exponentiation|url=https://mathworld.wolfram.com/Exponentiation.html|access-date=2021-12-29|website=mathworld.wolfram.com|language=en}}</ref> In general, the exponent (or superscript) indicates how many times the base appears in the expression, so that the expression
:<math>a^n = \underbrace{a\times a \times \cdots  \times a}_n = \prod_{i=1}^{n}a </math>
indicates that ''n'' copies of the base ''a'' are to be multiplied together. This notation can be used whenever multiplication is known to be [[Power associativity|power associative]].
