Answer 2

$\Large\boxed{\begin{array}{l}\underline{\rm D~\!\!efinic_{\!\!,}\tilde ao\,de\,fatorial}\\\sf n!=\begin{cases}\sf1,~~se~n=0~ou~n=1\\\sf n\cdot(n-1)\cdot(n-2)\cdot...3\cdot2\cdot1,~~se\,n\ne1\end{cases}\end{array}}$

$\Large\boxed{\begin{array}{l}\sf5!=5\cdot4\cdot3\cdot2\cdot1=120\\\sf 3!=3\cdot2\cdot1=6\\\sf 5!-3!=120-6=114\\\huge\boxed{\boxed{\boxed{\boxed{\sf\red{\maltese}\blue{~alternativa~c}}}}}\end{array}}$
