How to read exponents
For whole positive exponents, 2^10 means multiplying ten 2s together, which equals 1024. Fractional and negative exponents represent roots and reciprocals.
Example
2^10 equals 1,024 because the base 2 is multiplied by itself 10 times. 2^-3 equals 1 / 2^3, or 0.125.
Common mistakes
Negative bases with fractional exponents can move outside real-number arithmetic. Use care when combining negative values, roots and decimals.
Limitations
Logarithms answer the inverse question: which exponent produces a given value from a chosen base? This calculator returns numeric values, not symbolic simplification.
