Type the number being raised to a power. The base can be any positive or negative number, fraction, or decimal.

Type the power. Positive exponents multiply the base by itself N times. Negative exponents take the reciprocal. Fractional exponents give roots.

See the result, the math step by step, and the result in scientific notation for very large or very small numbers.

Exponent rules: a^m x a^n = a^(m+n). a^m / a^n = a^(m-n). (a^m)^n = a^(m*n). These rules are the foundation of scientific notation and logarithm math.
Scientific notation: Numbers are written as a x 10^b where 1 1 to 10le; a 1 to 10lt; 10. Useful for very large (1.5 x 10^23) or very small (6.022 x 10^-23) numbers in science and engineering.
Logarithms: The inverse of exponents. log(100) = 2 because 10^2 = 100. Natural log ln(x) uses base e (~2.718). For complex exponent math, use the scientific calculator.
