Answer 2

9!

= 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 72 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 504 × 6 × 5 × 4 × 3 × 2 × 1

= 3.024 × 5 × 4 × 3 × 2 × 1

= 15.120 × 4 × 3 × 2 × 1

= 60.480 × 3 × 2 × 1

= 181.440 × 2 × 1

= 362.880 × 1

= 362.880

6!

= 6 × 5 × 4 × 3 × 2 × 1

= 30 × 4 × 3 × 1

= 120 × 3 × 2 × 1

= 360 × 2 × 1

= 720 × 1

= 720

Jawaban no 1 :

= 9! + 6!

= 362.880 + 720

= 363.600

10!!

= 10 × 8 × 6 × 4 × 2 × 1

= 80 × 6 × 4 × 2 × 1

= 480 × 4 × 2 × 1

= 1.920 × 2 × 1

= 3.840 × 1

= 3.840

8!!

= 8 × 6 × 4 × 2 × 1

= 48 × 4 × 2 × 1

= 192 × 2 × 1

= 384 × 1

= 384

Jawaban no 2 :

= 10!! + 8!!

= 3.840 + 384

= 4.224
