F)3!/2!
G)12!/10!
H)4!+5!/4!
I) (n+1)!/(n-1)!

Answer 1

Resposta:

Explicação passo-a-passo:

a)8!/9! = 8! /9 . 8! = 1/9

b)15!/13! = 15 . 14 . 13! /13 ! = 15 . 14 = 210/1 = 210

c) 4!/6! = 4 ! / 6 . 5 . 4 ! = 1/30

d)6! /5 ! . 2! = 6 . 5 ! /5 ! 2 . 1 = 6/ 2 = 3

e) 8 ! / 4 ! . 6 ! = 8 . 7 . 6 ! / 4! .6! = 56 / 4.3.2.1 =56/24 =7/3

f)2 . 4! / 41 . 4! =2/4! =2/4.3.2!= 1/12

Espero ter ajudado
