Question

me ajudem, por favorrrrr

Answer 1

Resposta:

Desenvolvendo os fatoriais :

a) 6!= 6.5.4.3.2.1 = 30.24 = 720

b) 4.2! = 4.(2.1) = 4.2 = 8

c) O! + 4! = 1 + 4.3.2.1 = 1 + 24 = 25

d) 5! - 4! = 5.4.3.2.1- 4.3.2.1 = 120-24 = 96

e) 10!/3!.7! = 10.9.8.7/3.2.1.7!= 10.9.8/3.2 = 10.3.4

= 120

f) 15!.13!/14!.12! = 15.14!.13.12!/14!.12! = 15. 13 =

195

g) 12!.3!/15! = 12!.3.2.1/15.14.13.12! = 6/15.14.13 =

6/2 730=1/455

h) 7!/4!+3! = 7.6.5.4.3.2.1/4.3.2.1+3.2.1 = 5

040/24+6 = 5 040/30 = 168

i) (3!-0!)/3!2! = (3.2.1-1)/3.2.1.2.1 = (6-1)/6.2 = 5/12

ok
