How the Exponent Calculator works.
y = bˣb is the base and x is the exponent. The real-number result is evaluated with finite numeric arithmetic.
Worked example for the Exponent Calculator.
2 raised to the fourth power is 16 because 2 × 2 × 2 × 2 equals 16. A negative exponent takes the reciprocal: 10 raised to −3 is 0.001. A fractional exponent can mean a root: 9 raised to 0.5 is 3. Keep the parentheses around a negative base when you mean to raise that entire number to a power.
How to read this result.
The result is a real-number power when JavaScript’s real arithmetic can represent it; scientific notation is included for very large or small finite values.
How the calculation works
Exponentiation multiplies a base by itself for a positive whole exponent and extends the relationship to zero, negative, and fractional exponents where defined. Formula or rule: y = bˣ. b is the base and x is the exponent. The real-number result is evaluated with finite numeric arithmetic.
What this calculator does not prove
Floating-point output is approximate for many fractions. The tool does not perform symbolic algebra, complex-number evaluation, or arbitrary-precision decimal arithmetic. Use the result for the mathematical question shown here; a correct calculation does not by itself establish that the source data, sample, or real-world assumption is appropriate.
Inputs and edge cases to check.
Zero to a negative exponent, negative bases with non-integer exponents, non-finite inputs, and overflow are rejected. Enter the entire negative base explicitly when its sign is part of the value being raised to the exponent.
