Question

1- Efetue:

a)
$\frac{6!}{3x2!}$
b)
$\frac{10! + 9!}{11!}$
​

Answer 1

6!/3•2! = 720/3•2 =720/6 =120

10!+9!/11! =

10!/11! + 9!/11! =

10!/11.10! + 9!/11.10.9! =

1/11 + 1/110

10/110 + 1/110

11/110

Answer 2

Olá,

a)

$\frac{6!}{3 \times 2!} = \frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{3 \times 2 \times 1} = 6 \times 5 \times 4 = 120$

b)

$\frac{10! + 9!}{11!} = \frac{10! + 9!}{11 \times 10!} = \frac{9!}{11} = \frac{362880}{11} = 32989.09090909$

Espero ter ajudado :-) Bons estudos.
