Question

Simplifique os fatorias a seguir:
a) 8!/6!
b)13!/10!

Answer 1

primeiro vamos resolver 8!/6!

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

40320/720=56

8!/6! = 56

agora vamos resolver 13!/10!

13! = 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 6227020800
10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 3628800

6227020800/3628800=1716

13!/10!=1716
