$\dfrac{1}{8}a^5$

Work Step by Step

Multiplying the constants and multiplying the variables, the given expression, $\left( -\dfrac{1}{2}a^3 \right)\left( -\dfrac{1}{4}a^2 \right) ,$ simplifies to \begin{array}{l}\require{cancel} \left( -\dfrac{1}{2} \right)\left( -\dfrac{1}{4} \right)a^{3+2} \\\\= \dfrac{1}{8}a^5 .\end{array}
