Exponent Calculator

Raise any base to any power and see the result, including its scientific notation.

What this calculator does

Enter a base and an exponent and this calculator returns the power, shown in full and in scientific notation for very large or small results.

It handles negative and fractional exponents too — a fractional exponent is a root.

Worked example

On the values this calculator opens with, the result is 1.02K. Alongside it, Scientific comes out at 1.0240e+3. Change any field and every figure updates as you type.

Step by step

  1. Enter the base.
  2. Enter the exponent (negative or fractional is fine).
  3. Read the result and its scientific form.

The calculation

result = base ^ exponent negative exponent = 1 ÷ base^|exp| · fractional exponent = a root

Questions people ask about this

What does a negative exponent mean?
It’s the reciprocal: 2⁻³ = 1 ÷ 2³ = 0.125.
What does a fractional exponent mean?
It’s a root: 9^(1/2) is the square root of 9 = 3, and 8^(1/3) is the cube root = 2.
Why scientific notation?
Very large or small powers are easier to read as, say, 1.024 × 10³ than as a long string of digits.
