Answer:

(\dfrac{1}{4})^{\dfrac{-3}{2}} = 8

Step-by-step explanation:

The given expression is :

(\dfrac{1}{4})^{\dfrac{-3}{2}}

We know that,

\dfrac{1}{x}=x^{-1}

So,

(\dfrac{1}{4})^{\dfrac{-3}{2}}=(\dfrac{1}{2^2})^{\dfrac{-3}{2}}\\\\=(2^{-2})^{\dfrac{-3}{2}}\\\\=(2^{-1})^{-3}\\\\=2^3\\\\=8

So, the value of the given expression is 8.
