Note 1 to entry: The term "power" is also used for an expression representing an exponentiation.

Note 2 to entry: In the power *a*^{b}, *a* is the base and *b* is the exponent. The power is expressed by the words "*a* to the power *b*" or simply "*a* to *b*".

Note 3 to entry: The power with exponent 2 is the square, ${a}^{2}=a\cdot a$, the power with exponent 3 is the cube, ${a}^{3}=a\cdot a\cdot a$, the power with exponent −1 is the inverse, ${a}^{-1}=1/a$, the power with exponent 1/2 is the square root, ${a}^{1/2}=\sqrt{a}$.
