How it works
An exponent means multiplying the base by itself a certain number of times. A negative exponent means first finding the positive power, then taking its reciprocal (1 ÷ result). A fractional exponent of 0.5 means square root, and 1/3 means cube root.
Example 1: 210 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 1024.
Example 2: 2-2 = 1 ÷ 2² = 1 ÷ 4 = 0.25. And 90.5 = √9 = 3.
How to use

- Type the power in the Exponent (n) box.
- Read the result and the step-by-step working shown below.
- For common operations, use the quick buttons: Square, Cube, Square Root or Cube Root.
Good to know
- A negative exponent means one divided by the power — for example, 2 to the power -3 equals 1/8.
- An exponent of 0.5 is the same as the square root.
- Any number to the power of 0 equals 1.
