To find the root of the expression $$-\sqrt[4]{16}$$, we first need to calculate $$\sqrt[4]{16}$$.

1. **Calculate $$\sqrt[4]{16}$$**:
   - The fourth root of 16 can be expressed as $$16^{1/4}$$.
   - Since $$16 = 2^4$$, we have:
   $$
   \sqrt[4]{16} = (2^4)^{1/4} = 2^{4 \cdot \frac{1}{4}} = 2^1 = 2
   $$

2. **Apply the negative sign**:
   - Now, we apply the negative sign to the result:
   $$
   -\sqrt[4]{16} = -2
   $$

Thus, the root is $$-2$$.

Now, we can fill in the answer box:

A. $$-\sqrt[4]{16} = -2$$
A. $$-\sqrt[4]{16} = -2$$
