Exponent

Exponents in Algebra

In algebra, an exponent is a mathematical notation representing the number of times a base is multiplied by itself. A small raised number denotes the exponent to the right of the base. It indicates the power to which the base is raised.

If $a$ is the base and $n$ is the exponent, the expression is written as $a^n$ , where $a$ is multiplied by itself $n$ times.

Examples of Exponents

$2^3$ means $2$ raised to the power of $3$ , which is $2\times2\times2=8$ .
$5^2$ means $5$ raised to the power of $2$ , which is $5\times5=25$ .
$3^4$ means $3$ raised to the power of $4$ , which is $3\times3\times3\times3=81$ .
$10^0$ means $10$ raised to the power of $0$ , which is always $1$ (any nonzero number raised to the power of $0$ is $1$ ).
$x^2$ means $x$ raised to the power of $2$ , which is $x^x$ .
