How to use

Enter the number whose root you need.
Enter the degree: 2 = square root, 3 = cube root, 4 = fourth root, and so on.
The result also includes a check (the result raised to the power n).

Note: the root of a negative number is only real for an odd degree (3, 5, 7...); for an even degree there is no real result.
