The answer will depend on the form of the fourth root. Positive real numbers will have two fourth roots which are real and two that are complex. Complex numbers will have four complex roots. However, none of these can be "simplified" in the normal sense of the term.

Usually four. As a simple example, the fourth roots of 1 are: 1, -1, i, -i.
The square roots of 13 cannot be simplified.
Fourth roots are the inverse operation of raising a number to the fourth power. For a given number, the fourth root is a number that, when raised to the fourth power, equals the original number. For example, the fourth root of 16 is 2, since 2^4 = 16. In mathematical notation, the fourth root of a number x is denoted as √√x or x^(1/4).
There are 3 cube roots of 27. There are 2 square roots of 27 ( or any real number ). There are 4 fourth roots of 27 and so on:)
