Answer:
1.25
Step-by-step explanation:
Given:
Consider the given expression is:

To find:
The simplified form of the given expression.
Solution:
We have,

By using the quotient property of exponents, we get
![\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5Cright%5D)


By using negative exponent property, we get
![\left[\because a^{-n}=\dfrac{1}{a^n}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5Cright%5D)
The simplified form of the given expression is
.
Therefore, the correct option is B.
