Question

calcule qual seria a resposta 
6!
3!-2!
5.3!
7!+5!

Answer 1

$6! = 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1 = \boxed{720} \\\\ 3!-2! = (3 \cdot 2 \cdot 1)-(2 \cdot 1) = 6-2 = \boxed{4} \\\\ 5 \cdot 3! = 5 \cdot (3 \cdot 2 \cdot 1) = 5 \cdot 6 = \boxed{30} \\\\ 7!+5! = (7 \cdot 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1) + (5 \cdot 4 \cdot 3 \cdot 2 \cdot 1) = \\ = 5040+120 = \boxed{5160}$
