To show the negative of a square root, a negative sign would have to be placed outside the radical. When working with other roots, note that when the index is odd, a negative radicand can be produced by negative factors.
Similarly, Does the square root of 4 equals negative 2? The value of root 4 is equal to exactly 2. But the roots could be positive or negative or we can say there are always two roots for any given number. Hence, root 4 is equal to ±2 or +2 and -2 (positive 2 and negative 2).
