About this calculator
The UTIQO Root Calculator computes the nth root of a given number, supporting both integer and fractional indices, and returns the principal real root along with alternative forms such as decimal and scientific notation. The calculator evaluates the expression x^(1/n) using the standard power function.

Frequently asked questions
What is the nth root of a number?
The nth root of a number x is a value r such that r^n = x. For even n, the principal root is non-negative; for odd n, negative radicands yield negative roots.
Can I compute the square root of a negative number?
No, the square root of a negative number is not a real number. This calculator returns an error for such inputs.
What if the index is a fraction?
The calculator supports fractional indices, e.g., index 1/2 is equivalent to square root. However, for negative radicands, fractional indices may not yield real results.
