The fourth square root is the 16th root of a number.
On a computer, to find the 16th root of a number, say 5.6, enter 5.6^(1/16).
If the number you start with is positive, you will have 2 real roots (one positive and one negative) and 14 complex roots. If it is negative, you will have 16 complex roots.
