Answer 2

$\textcolor{red}{\frac{5!-3!}{2!}}$

$\textcolor{red}{\frac{5.4.3.2!-3.2!}{2!}}$

$\textcolor{red}{\frac{\cancel{2!}(5.4.3-3)}{\cancel{2!}}}$

$\textcolor{red}{5.4.3-3=60-3}$

$\textcolor{green}{=57}\textcolor{blue}{\checkmark}$

Ou

$\textcolor{red}{5!-\frac{3!}{2!}}$

$\textcolor{red}{5!-\frac{3.\cancel{2!} }{\cancel{2!}}}$

$\textcolor{red}{5!-3=120-3}$
