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.

What does it mean if there are two square root symbols over a number?
Take the square root of the square root of the number (that is the fourth root of the number), for example: √√16 = √(√16) = √4 = 2 24 = 16 ⇒ 2 is the fourth root of 16.
Can a square root of a perfect square be another perfect square?
Sure. Take the fourth power of any natural number, for example 24 = 16. It square root is a perfect square, in this case 22. As another example, the square root of 34 = 32.
