Question

Simplifique as expressões:

3!/2!
12!/10!
4!+5!/4!
8!/6!+5

POR FAVOR ALGUEM ME AJUDA NAO CONSEGUI ENTENDER ESSA MATERIA.

Answer 1

3! / 2! = 3.2! / 2! = 3

12! / 10! = 12.11.10! / 10! = 12.11 = 132

(4! + 5!) / 4! = (4! + 5.4!) / 4! = 4!(1 + 5) / 4! = 6

8! / (6! + 5!) = 8.7.6.5! / (6.5! + 5!) = 336.5! / (5!(6 + 1)) = 336 / 7 = 48
