## Exponent

### A number that shows repeated multiplication.

An exponent is a mathematical notation that indicates the number of times a quantity is multiplied by itself. It is usually written as a raised superscript number next to the base number. For example, in the expression 2^3, 2 is the base number and 3 is the exponent. This means that 2 is multiplied by itself three times, resulting in an answer of 8 (2 x 2 x 2 = 8).

Exponents are commonly used in mathematical equations and scientific notation to represent large or small numbers. They also have specific rules for operations, such as the properties of exponents, which simplify expression with exponents. For example, when multiplying two exponential expressions with the same base, we can add the exponents together (a^x * a^y = a^(x+y)).

Exponents are an important concept in mathematics and have many applications in real-world scenarios, such as in calculating compound interest, measuring radioactive decay, and analyzing population growth.
