Answer
$\dfrac{5!}{3!}=20$
Work Step by Step
Using $n!=n(n-1)(n-2)...(3)(2)(1),$ the value of the given expression, $
\dfrac{5!}{3!}
,$ is
\begin{align*}\require{cancel}
&
\dfrac{5(4)(3!)}{3!}
\\\\&=
\dfrac{5(4)(\cancel{3!})}{\cancel{3!}}
\\\\&=
5(4)
\\&=
20
.\end{align*}
Hence, $
\dfrac{5!}{3!}=20
$.
