Yes, it is a rational number.
For this case we have that by definition of power properties it is fulfilled that:
![a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}](https://tex.z-dn.net/?f=a%20%5E%20%7B-1%7D%20%3D%20%5Cfrac%20%7B1%7D%20%7Ba%20%5E%201%7D%20%3D%20%5Cfrac%20%7B1%7D%20%7Ba%7D)
So, if we have the following expression:
![-5x^{-4}](https://tex.z-dn.net/?f=-5x%5E%7B-4%7D)
We can rewrite it as:
![\frac {-5} {x ^ 4} = - \frac {5} {x ^ 4}](https://tex.z-dn.net/?f=%5Cfrac%20%7B-5%7D%20%7Bx%20%5E%204%7D%20%3D%20-%20%5Cfrac%20%7B5%7D%20%7Bx%20%5E%204%7D)
Answer:
![- \frac {5} {x ^ 4}](https://tex.z-dn.net/?f=-%20%5Cfrac%20%7B5%7D%20%7Bx%20%5E%204%7D)
