^ Exponent & Root Calculator
Compute a^b for any real base and exponent — integer, decimal, or negative. Also compute nth roots (square root, cube root, etc.). For even roots of negative numbers we display the complex result.
Examples
7²49∛12552^-30.1258^(1/3)2Frequently asked questions
What is 0^0?
By convention 1 in combinatorics and most programming. Some mathematicians leave it undefined. We return 1.
Why is √(-4) complex?
No real number squared equals -4. The principal complex square root is 2i. We show both the real and complex result for negative inputs.
How accurate are roots?
IEEE 754 doubles — about 15 significant digits. For exact integer roots we detect and return integers.
