STEP 1

1. We are asked to find the fourth root of $625$ and then apply a negative sign.
2. The fourth root of a number $x$ is a number $y$ such that $y^4 = x$.
3. We need to determine if the result is a real number.

STEP 2

1. Determine the fourth root of $625$.
2. Apply the negative sign to the root.
3. Verify if the result is a real number.

STEP 3

Determine the fourth root of $625$.
$$y^4 = 625$$ Find $y$ such that $y^4 = 625$.

STEP 4

Recognize that $625 = 5^4$.
Therefore, the fourth root of $625$ is $5$.
$$\sqrt[4]{625} = 5$$

STEP 5

Apply the negative sign to the root.
$$-\sqrt[4]{625} = -5$$

Verify if the result is a real number.
Since $-5$ is a real number, the answer is a real number.
The correct choice is:
A. The answer is $-5$.
