Concept

Exponent

An exponent is a number or expression written above a number, indicating that it is being multiplied by itself. The notation is made up of a base — the number being multiplied — and an exponent, which gives the number of times the base appears in the multiplication.

The resulting number is commonly called a power. In this example, the base is multiplied by itself times. Most exponential expressions are read in the same way, whether they are numeric or algebraic.

Expression Example Example
raised to the power of raised to the fourth power
to the power of to the ninth power
to the second squared
to the third cubed

Notice in the examples above that two special cases were included; when a number or variable is raised to the power of or the exponential expression can be read as squared or cubed, respectively.
