Quis.1. 6!2. 5! + 7! – 3!​

1. 6!

= 6 x 5 x 4 x 3 x 2 x 1

= 720

2. 5! + 7! -3!

= (5 x 4 x 3 x 2 x 1) + (7 x 6 x 5 x 4 x 3 x 2 x 1) – (3 x 2 x 1)

= (3 x 2 x 1) x ((5 x 4) + (7 x 6 x 5 x 4) – 1)

= 6 x (20 + 840 – 1)

= 6 x 859

= 5.154

Jawaban:

1. = 6!

= 6 x 5 x 4 x 3 x 2 x 1

= 720

2. = 5! + 7! – 3!

= 5.4.3.2.1 + 7.6.5.4.3.2.1 – 3.2.1

= 120 + 5.040 + 6

= 5.164
