Answer 1

Resposta:

Explicação passo-a-passo:

$\frac{8!}{6!}=8*7=56$

$\frac{7!}{6!}=7$

$3!+4!-0!= (3*2*1)+(4*3*2*1)-1=6+24-1=29$

$\frac{2!}{0!}=2$

$2(3!+2!)=6!+4!=(6*5*4*3*2*1)+(4*3*2*1)=720+24=744$

$(-2)!= (-2)*(-1)=2$

$0!+2!-1!-3!=1+2-1-6=-4$

$\frac{8!}{(5!*2!)}=\frac{8*7*6}{2*1}= \frac{336}{2}= 168$
