$3,458$

#### Work Step by Step

Substituting $s=4$ and $t=8$, the given expression, $\dfrac{(3s)^3t+t}{s} ,$ evaluates to \begin{array}{l}\require{cancel} \dfrac{(3\cdot4)^3(8)+8}{4} \\\\= \dfrac{(12)^3(8)+8}{4} \\\\= \dfrac{(1728)(8)+8}{4} \\\\= \dfrac{13824+8}{4} \\\\= \dfrac{13832}{4} \\\\= 3,458 .\end{array}
