Obrigado desde ja

Answer 1

$\boxed{\mathtt{n!= n\cdot(n-1)\cdot (n-2)\cdot(n-3)\cdot\dotsc\cdot1}}$

$\mathsf{ \dfrac{5!}{(5-3)!}=\dfrac{5\cdot(5-1)\cdot(5-2)\cdot(5-3)\cdot1}{2\cdot1}}$

$\mathsf{\dfrac{5!}{(5-3)!}=\dfrac{5\cdot4\cdot3\cdot2\cdot1}{2\cdot1} }$

$\mathsf{ \dfrac{5!}{(5-3)!}=\dfrac{120}{2}}$

$\boxed{\boxed{ \mathbf{ \dfrac{5!}{(5-3)!}=60}}}$
