Answer 1

soal 1 :

19!!

= 19 × 17 × 15 × 13 × 11 × 9 × 7 × 5 × 3 × 1

= 323 × 15 × 13 × 11 × 9 × 7 × 5 × 3 × 1

= 4.845 × 13 × 11 × 9 × 7 × 5 × 3 × 1

= 62.985 × 11 × 9 × 7 × 5 × 3 × 1

= 692.835 × 9 × 7 × 5 × 3 × 1

= 6.235.515 × 7 × 5 × 3 × 1

= 43.648.605 × 5 × 3 × 1

= 218.243.025 × 3 × 1

= 654.729.075 × 1

= 654.729.075

7!!

= 7 × 5 × 3 × 1

= 35 × 3 × 1

= 105

penyelesaian :

= 19!! - 7!!

= 654.729.075 - 105

= 654.728.970

soal 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

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

penyelesaian :

= 9! × 7!

= 362.880 × 5.040

= 1.828.915.200
