Exponent Calculator
The Exponent Calculator quickly computes powers of numbers using any base and exponent. It supports positive exponents, negative exponents, decimal exponents, and zero exponents, making it useful for students, engineers, scientists, and professionals.
What Is an Exponent?
An exponent tells how many times a number (called the base) is multiplied by itself. Exponents are also known as powers or indices.
For example:
5² = 5 × 5 = 25
2⁵ = 2 × 2 × 2 × 2 × 2 = 32
Exponent Formula
aⁿ = a × a × a × ... (n times)
For negative exponents:
a⁻ⁿ = 1 / aⁿ
For zero exponents:
a⁰ = 1 (when a ≠ 0)

Rules of Exponents
- am × an = am+n
- am ÷ an = am−n
- (am)n = amn
- (ab)n = anbn
- a−n = 1/an
- a0 = 1
Frequently Asked Questions
What is an exponent?
An exponent indicates how many times a base number is multiplied by itself.
Can exponents be negative?
Yes. A negative exponent represents the reciprocal of the positive exponent.
Can exponents be decimals?
Yes. Decimal exponents are supported and represent roots and fractional powers.
What happens when the exponent is zero?
Any non-zero number raised to the power of zero equals 1.
