Question

calcule o fatorial

0!+1!=

3!+2!=

7!-5!=

5.3!=

Answer 1

0! = 1
1! = 1

(Propriedades do fatorial) = 1 + 1 = 2

3! + 2! = 3 . 2 . 1 + 2 . 1
6 + 2 = 8

7! - 5! = 7 . 6 . 5 . 4 . 3 . 2 . 1 - 5 . 4 . 3 . 2 . 1 = 5040 - 120 = 4920

5 . 3! = 5 . 3 . 2 . 1 = 30

Answer 2

Calcule o fatorial

0!+1!=  1 +1 ==> 2

3!+2!= 3.2.1.+ 2.1 ==> 6+2==> 8

7!-5!= 7.6.5.4.3.2.1 - 5.4.3.2.1 ==> 5040 - 120 ==> 4920

5.3!= 5.3.2.1 ==> 30
