Question

numero fatorial. (8!-4!+3! / 5!+3!-6!=

Answer 1

8! = 8.7.6.5.4.3.2.1 = 40.320
4! = 4.3.2.1 = 24
3! = 3.2.1 = 6
Portanto, 40.320-24+6= 40.302

5! = 5.4.3.2.1 = 120
3! = 3.2.1 = 6
6! = 6.5.4.3.2.1 = 720
120+6-720= 594

Então, 40.302/594= 67.848

Answer 2

8!-4!+3! / 5!+3!-6!

8! - 4! + 3!       
-------------------
  5! + 3! - 6!

8! = 8.7.6.5.4.3.2.1 = 40320
4! = 4.3.2.1 = 24
3! = 3.2.1 = 6

5! = 5.4.3.2.1 = 120
3! = 3.2.1 = 6
6! = 6.5.4.3.2.1 = 720

40320 - 24 + 6       =  40320 - 18     =  40302
------------------------     -----------------      -----------
120 + 6 - 720              126 - 720            - 594

= - 40302     (:2)      -  20151
     -----------         =     -----------
        594      (:2)            297
