What Is an Exponent?
An exponent (also called a power) tells you how many times a number is multiplied by itself.
For example:
5³ = 5 × 5 × 5 = 125
In this example:
- 5 is the base.
- 3 is the exponent.
- 125 is the result.
Exponents are widely used in mathematics, science, engineering, finance, and computer programming.

Common Exponent Rules
Learning a few basic exponent rules can make solving math problems much easier.
Zero Exponent Rule
Any non-zero number raised to the power of zero equals 1.
Example:
2⁰ = 1
10⁰ = 1
Negative Exponent Rule
A negative exponent means you take the reciprocal of the positive exponent.
Formula:
x⁻ⁿ = 1 / xⁿ
Example:
2⁻³ = 1 / 8 = 0.125
Power of a Power Rule
When raising a power to another power, multiply the exponents.
Formula:
(xᵐ)ⁿ = xᵐⁿ
Example:
(2³)² = 2⁶ = 64
Fractional Exponents
Fractional exponents represent roots.
Example:
9¹⁄² = √9 = 3
16¹⁄⁴ = 2
