tentukan nilai 7!/3!??

Faktorial
[tex]n! = n \times (n-1) \times (n-2) \times .... \times 3 \times 2 \times 1 \\ 5! = 5 \times 4 \times 3 \times 2 \times 1 \\ 6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 \\ \\ \frac{7!}{3!} = \frac{7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}{3 \times 2 \times 1} \\ \frac{7!}{3!} = 7 \times 6 \times 5 \times 4 \\ \frac{7!}{3!} = 840[/tex]

4! = 4.3.2.1
maka 7!/3! =
7.6.5.4.3!/3!
7.6.5.4= 840.
maaf klo salahhhh.....
