How our exponent calculator works

1

Enter the base

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

2

Enter the exponent

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

Key things to know about our exponent calculator:

  • 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.

How it works

How to calculate any number raised to any power

Our exponent calculator lets you find the result of any base raised to any exponent, including negative and fractional powers.

  1. 1

    Enter the base

    Type the base number. The exponent calculator accepts any positive or negative number, including decimals and fractions. For square root, use 1/2 as the exponent; for cube root, use 1/3.

  2. 2

    Enter the exponent

    Type the power. The exponent calculator accepts positive, negative, zero, and fractional exponents. Scientific notation is supported (e.g. 1.5e-3). The exponent calculator computes the result with full precision.

  3. 3

    Read the result

    The result shows the exact value in decimal and scientific notation, plus the steps for simple cases. The exponent calculator also shows the modular version (mod n) if needed. The share button creates a link with your inputs pre-filled.
