Exponent Calculator
What is an Exponent?
An exponent indicates how many times a number is multiplied by itself. It is commonly written as:
aⁿ
Here, a is the base and n is the exponent.
For example:
2⁵ = 2 × 2 × 2 × 2 × 2 = 32
Therefore, the value of 2 raised to the power of 5 is 32.
How to Use the Exponent Calculator
Using this online exponent calculator is simple:
- Enter the base number.
- Enter the exponent or power.
- Click the Calculate button.
- The calculator will display the result instantly.
For example, if you enter 5 as the base and 3 as the exponent:
5³ = 125
Examples of Exponents
| Base | Exponent | Calculation | Result |
|---|---|---|---|
| 2 | 3 | 2 × 2 × 2 | 8 |
| 3 | 4 | 3 × 3 × 3 × 3 | 81 |
| 5 | 2 | 5 × 5 | 25 |
| 10 | 3 | 10 × 10 × 10 | 1000 |
| 7 | 2 | 7 × 7 | 49 |
Negative Exponents
The calculator can also calculate negative exponents.
A negative exponent represents the reciprocal of the positive power:
a⁻ⁿ = 1 / aⁿ
For example:
2⁻³ = 1 / 2³ = 1 / 8 = 0.125
Decimal Exponents
Decimal exponents can also be used for calculations involving roots and fractional powers.
For example:
9⁰·⁵ = √9 = 3
Therefore, an exponent calculator can be useful for both basic and more advanced mathematical calculations.

Exponent Formula
The basic exponent formula is:
aⁿ = a × a × a × … × a
where the base a is multiplied by itself n times.
For example:
4³ = 4 × 4 × 4 = 64
