What this calculator estimates
Calculate a base raised to an exponent plus common related powers and roots.
How to use it
Enter Base x; Exponent y. Select Calculate to update the results.
How the calculation works
The main result uses exponentiation, multiplying the base by itself according to the entered exponent.
Worked example: starting scenario
| Base x | 5 |
|---|---|
| Exponent y | 4 |
| x raised to y | 625 |
|---|---|
| x squared | 25 |
| x cubed | 125 |
| Square root of |x| | 2.2360679775 |
| Reciprocal of x | 0.2 |
Important limitations
Large powers can exceed browser numeric limits, and negative bases with non-integer exponents may not produce a real-number result.
Powers, reciprocals and real-domain limits
For base 2 and exponent −3, the power is 1/8 = 0.125. A fractional exponent of a negative base can fall outside the real-valued browser operation used here; it should not be interpreted as zero. The root helper uses the absolute base as labelled, and the reciprocal requires a nonzero base. Huge or extremely tiny powers can fall outside the representable numeric range.
