What are exponents? Exponential notation is a form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter written above and to the right of a mathematical expression called the base. It indicates that the base is to be raised to a certain power. x is the base and n is the exponent or power.

**Definition:
If x is a positive number and n is its exponent, then x ^{n} means
x is multiplied by itself n times.**

**Examples:**

3^{2}
= 3 x 3

3^{5
}= 3 x 3 x 3 x 3 x 3
