Answer

$\dfrac{81}{16}$

Work Step by Step

Using $a^{-x}=\dfrac{1}{a^x}$ or $\dfrac{1}{a^{-x}}=a^x$ and the laws of exponents, the given expression, $ \dfrac{1}{\left( \dfrac{3}{2} \right)^{-4}} ,$ is equivalent to \begin{array}{l}\require{cancel} \left( \dfrac{3}{2} \right)^{4} \\\\= \dfrac{3^4}{2^4} \\\\= \dfrac{81}{16} .\end{array}
