7! = ….

= (7 × 6 × 5 × 4 × 3 × 2 × 1)

= (42 × 5 × 4 × 3 × 2 × 1)

= (210 × 4 × 3 × 2 × 1)

= (840 × 3 × 2 × 1)

= (2.520 × 2 × 1)

= (5.040 × 1)

= 5.040

5! =….

= (5 × 4 × 3 × 2 × 1)

= (20 × 3 × 2 × 1)

= (60 × 2 × 1)

= (120 × 1)

= 120

6! = …..

= (6 × 5 × 4 × 3 × 2 × 1)

= (30 × 4 × 3 × 2 × 1)

= (120 × 3 × 2 × 1)

= (360 × 2 × 1)

= (720 × 1)

= 720

7! + 5! – 6! = ??

= 5.040 + 120 – 720

= 5160 – 720

= 4.440

ºJawaban...

1) 7! + 5! – 6! = ??

__________________

= 7! + 5! – 6!

= (7.6.5.4.3.2) + (5.4.3.2) – 6!))

= (5040 + (120 – (6.5.4.3.2))

= 5160 – 720

= 4.440
