Exponent Root Calculator
Calculate powers and nth roots locally in your browser.
Enter a radicand from -1000000000000000 to 1000000000000000 and a whole-number degree from -1000 to 1000. For example, the 2nd root of 144 is 12, and the 3rd root of 27 is 3. The calculation runs locally in your browser; your values are not uploaded or stored.
Find a power or an nth root without uploading anything.
Choose Power to raise a base from -1000000 to 1000000 to an exponent from -1000 to 1000, or Nth root to find the root of a value from -1000000000000000 to 1000000000000000 with a whole-number degree from 2 to 1000. Everything runs locally in your browser, so your values are not uploaded or stored.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What is an nth root?
The nth root of a number is the value that, when raised to the power n, gives the original number. For example, the 2nd root of 144 is 12 because 12 x 12 = 144, and the 3rd root of 27 is 3 because 3 x 3 x 3 = 27.
What does the exponent root calculator show?
Enter a radicand from -1000000000000000 to 1000000000000000 and a whole-number degree from -1000 to 1000. The calculator returns the nth root and reports whether it is a perfect power. For example, the 2nd root of 144 gives 12 with perfect power Yes, while the 2nd root of 2 gives about 1.41421356237 with perfect power No.
Which inputs are accepted?
Enter a radicand from -1000000000000000 to 1000000000000000 and a whole-number degree from -1000 to 1000. A negative radicand needs an odd whole-number degree to keep a real result, and zero cannot have a negative-degree root. Non-numeric text, a degree of zero, and values outside these limits show a clear error instead of a result.
Do my numbers stay private?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter.
