Exponent Calculator
Exponent Calculator Online – Calculate Powers Easily
Intro
An Exponent Calculator online is a simple yet powerful tool that helps you calculate numbers raised to a power (exponents). In mathematics, an exponent tells us how many times a number (called the base) is multiplied by itself. For example, 24=2×2×2×2=162^4 = 2 \times 2 \times 2 \times 2 = 1624=2×2×2×2=16.
Exponents are widely used in algebra, physics, engineering, finance, and computer science. They make it easier to express very large or very small numbers, such as 10610^6106 (one million) or 10−310^{-3}10−3 (0.001).
Instead of solving exponents manually, the Exponent Calculator gives instant results, saving time and reducing mistakes. It’s useful for students, teachers, researchers, and professionals alike.
Formula / Working
The general formula for exponents is: an=a×a×a×…×a(n times)a^n = a \times a \times a \times \ldots \times a \quad (n \text{ times})an=a×a×a×…×a(n times)
Where:
- a = base (the number being multiplied)
- n = exponent or power (how many times to multiply the base)
Exponent Rules:
- Multiplication Rule:
am×an=am+na^m \times a^n = a^{m+n}am×an=am+n
- Division Rule:
aman=am−n\frac{a^m}{a^n} = a^{m-n}anam=am−n
- Power Rule:
(am)n=am×n(a^m)^n = a^{m \times n}(am)n=am×n
- Negative Exponent Rule:
a−n=1ana^{-n} = \frac{1}{a^n}a−n=an1
- Zero Exponent Rule:
a0=1a^0 = 1a0=1
The Exponent Calculator applies these rules instantly to provide accurate results.
