Question

fatrial Determine o valor de : 6!-4!​

Answer 1

Explicação passo-a-passo:

5! + 3!

= 5.4.3.2.1 + 3.2.1

= 120+6

= 126

5

* 5.0

6! - 4!

= 6.5.4.3.2.1 - (4.3.2.1)

= 720 - 24

= 696

5!/3!

= 5.4.3.2 /3.2

= 120/6

= 20

= (n+2) / n!

= (n+2).(n+1).n!/n!

= n^2 +n + 2n + 2

= n^2 + 3n + 2
