Given:
The expression is

To find:
The simplified form of the given expression so there is only one positive power for the baser -5.
Solution:
We have,


Using the properties of exponents, the given expression can be written as
![[\because \dfrac{a^m}{a^n}=a^{m-n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D)

Here, the base is -5 and the exponent is 5.
Therefore, the correct option is C.
