Question

Calcule:
a) 0! =
b) I! =
c) 2! =
d) 3!=
e) 4! =
f) 5! =
g) 2! - 1!
h) 5!/3!=
i) 10!/ 5!​

Answer 1

Resposta:

a) 0! = 1 (por convenção)

b) 1! = 1

c) 2! = 2 x 1 = 2

d) 3! = 3 x 2 x 1 = 6

e) 4! = 4 x 3 x 2 x 1 = 24

f) 5! = 5 x 4 x 3 x 2 x 1 = 120

g) 5!/3! = 120/6 = 20

h) 10!/5! = 10 x 9 x 8 x 7 x 6 x 5! ​/ 5! = 10 x 9 x 8 x 7 x 6 = 30 240
