Question

2.4!2!/4!4! Me socorre nessa tmb?

Answer 1

Olá, boa tarde! ☺

Prezado amigo (a), com base no enunciado acima podemos compreender que:

$\dfrac {2\cdot 4!2!}{4!4!}$

$\dfrac {2\cdot\not{4!}2!}{\not {4!}4!}$

$\dfrac {22!}{4!}$

$\dfrac {22!}{4\times 3\times 2!}$

$\dfrac {2!}{2\times 3\times 2!}$

$\dfrac {1}{2\times 3}$

$\boxed {\dfrac {1}{6}}$
