Question

exercicio calcule 6!+8!3!:=

Answer 1

6!=6*5*4*3*2*1! = 720
8!=8*7*6*5*4*3*2*1!=40,320
3!=3*2*1!=6
720+40,320*6=720+241,920=242,640

Answer 2

6! = 6.5.4.3.2.1 = 30.12.2 = 360.2 = 720
8! = 8.7.6.5.4.3.2.1 = 56.720 = 40320
3! = 3.2.1 = 6

= 6! + 8!.3!
= 6.5.4.3.2.1 + 8.7.6.5.4.3.2.1.3.2.1
= 720 + 40320.6
= 720 + 241920
= 242640
