  1. Check the input labels and enter the example values above.
  2. Apply the relationship: Result = base ^ exponent.
  3. The result is 256 , rounded for display.

How to interpret your result

Fractional and negative exponents are supported with positive bases.

Identify whether the question asks for one term, a total or a count of possible selections. Sequences use a fixed difference or ratio. In counting problems, order and replacement determine the correct model.

Frequently asked questions

Do combinations and permutations count the same thing?

No. Combinations ignore the order of selection; permutations count different orders separately.

How do I use the exponent calculator?

Enter base, exponent. The result updates automatically. Use the units shown beside each input; the example values illustrate the method.

Which formula does this calculator use?

Result = base ^ exponent.

What should I check before using the result?

Fractional and negative exponents are supported with positive bases.

How are results rounded?

Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
