In mathematics, exponentiation is the name for the operation also called raising to a power. In simple cases, it refers to repeated multiplication. It is indicated by a superscript, a small number or expression written above the line:
- 26, "two to the sixth power," 2×2×2×2×2×2 = 64
- x4, "x to the fourth power," x×x×x×x
- yn, "y to the n-th power," y×y×y× ... ×y, where y appears n times.
