Exponent Calculator (Powers)
Calculate powers and exponents for any base and number. Includes common power tables and exponent rules.
An exponent calculator raises any base to any power, displays the result with common power tables, and helps verify exponent rules for quick calculations.
Examples
Square of 5
5^2 = 25
Frequently Asked Questions
What is a negative exponent?
A negative exponent indicates a reciprocal: a^-n = 1 / a^n.
Key Terms

Quick Tips
- •Double-check your inputs — small errors in the exponent lead to exponentially large errors in the result.
- •Remember the key rules: a^0 = 1, a^-n = 1/a^n, and (a^m)^n = a^(m*n).
- •Use the power tables to quickly look up commonly needed values.

Assumptions & Limitations
- Assumes exact input values — rounding errors in the inputs will propagate to the result.
- Results may show floating-point approximations for irrational numbers.
- Very large exponents may produce numbers too large to display in full decimal form.
