Question

(fatorial). Calcule a)6! b)4!-3! c)0! .3! d)4! / 3! +2!​

Answer 1

Explicação passo-a-passo:

a)

$\sf 6!=6\cdot5\cdot4\cdot3\cdot2\cdot1$

$\sf 6!=30\cdot12\cdot2$

$\sf 6!=360\cdot2$

$\sf \red{6!=720}$

b)

• $\sf 4!=4\cdot3\cdot2\cdot1$

$\sf 4!=12\cdot2$

$\sf 4!=24$

• $\sf 3!=3\cdot2\cdot1$

$\sf 3!=6$

Assim:

$\sf 4!-3!=24-6$

$\sf \red{4!-3!=18}$

c)

$\sf 0!\cdot3!=1\cdot6$

$\sf \red{0!\cdot3!=6}$

d)

$\sf \dfrac{4!}{3!+2!}=\dfrac{24}{6+2}$

$\sf \dfrac{4!}{3!+2!}=\dfrac{24}{8}$

$\sf \red{\dfrac{4!}{3!+2!}=3}$
