Answer:
Solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get 
Step-by-step explanation:
We need to solve the expression:

We know the exponent rule: 

Now, another exponent rule says that: 

We also know that: 
=
So, solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get 
9 is the correct interpretation
