What is an Exponent Calculator?

The Exponent Calculator is a free, easy way to deal with powers (bⁿ), nth roots (ⁿ√a), and scientific notation (c × 10ⁿ). The calculator allows you to quickly evaluate large powers, simplify fractional or negative exponents, or rewrite values in exponential notation to help reduce manual mistakes. This calculator can quickly give you answers whether you are taking algebra, checking physics or engineering calculations, or getting results ready for a report written in a specific format.

Select a mode and follow these steps:

1. Basic Exponentiation - enter the base (b) and exponent (n), and select Calculate.
   • Example: 2⁸ = 256
   • Negative exponent: 5⁻² = 1/5² = 0.04
   • Fractional exponent: 27^(2/3) = (³√27)² = 9
2. Nth Root Calculation - enter the radicand (a) and the degree (n).
   • Example: ⁴√81 = 3
   • ∛(−125) = −5 (odd roots permit negatives, but even roots of negatives are not real).
3. Scientific Notation - enter the coefficient (c) and the power of 10 (n) so that c × 10ⁿ results.
   • Example: 3.2 × 10⁵ = 320,000
   • 6.7 × 10⁻³ = 0.0067

Formulas Used in Exponent Calculator

Exponentiation:
bⁿ (repeated multiplication).
When n is fractional, b^(p/q) = q√(b^p).

When :

• n < 0
• bⁿ = 1 / b^|n|
