Penyelesaian :
10! + 9!
= 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 + 9!
= 90 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 + 9!
= 720 × 7 × 6 × 5 × 4 × 3 × 2 × 1 + 9!
= 5.040 × 6 × 5 × 4 × 3 × 2 × 1 + 9!
= 30.240 × 5 × 4 × 3 × 2 × 1 + 9!
= 151.200 × 4 × 3 × 2 × 1 + 9!
= 604.800 × 3 × 2 × 1 + 9!
= 1.814.400 × 2 × 1 + 9!
= 3.628.800 × 1 + 9!
= 3.628.800 + 9!
=3.628.800+9 × 8 × 7 × 6 × 5 × 4 × 3 × 2×1
= 3.628.800 + 72 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 3.628.800 + 504 × 6 × 5 × 4 × 3 × 2 × 1
= 3.628.800 + 3.024 × 5 × 4 × 3 × 2 × 1
= 3.628.800 + 15.120 × 4 × 3 × 2 × 1
= 3.628.800 + 60.480 × 3 × 2 × 1
= 3.628.800 + 181.440 × 2 × 1
= 3.628.800 + 362.880 × 1
= 3.628.800 + 362.880
= 3.991.680 √
8!! - 6!!
= 8 × 6 × 4 × 2 - 6!!
= 48 × 4 × 2 - 6!!
= 192 × 2 - 6!!
= 384 - 6!!
= 384 - 6 × 4 × 2
= 384 - 6 + 6 + 6 + 6 × 2
= 384 - 12 + 6 + 6 × 2
= 384 - 18 + 6 × 2
= 384 - 24 × 2
= 384 - 48
= 336 √
7! × 5!
= 7 × 6 × 5 × 4 × 3 × 2 × 1 × 5!
= 42 × 5 × 4 × 3 × 2 × 1 × 5!
= 210 × 4 × 3 × 2 × 1 × 5!
= 840 × 3 × 2 × 1 × 5!
= 2.520 × 2 × 1 × 5!
= 5.040 × 1 × 5!
= 5.040 × 5!
= 5.040 × 5 × 4 × 3 × 2 × 1
= 5.040 × 20 × 3 × 2 × 1
= 5.040 × 60 × 2 × 1
= 5.040 × 120 × 1
= 5.040 × 120
= 604.800 √
4!! ÷ 3!!
= 4 × 2 ÷ 3!!
= 2 + 2 + 2 + 2 ÷ 3!!
= 4 + 2 + 2 ÷ 3!!
= 6 + 2 ÷ 3!!
= 8 ÷ 3!!
= 8 ÷ 3 × 1
= 8 ÷ 3
= 2,6 √
Keterangan :
→ hasil dari 10! + 9! adalah 3.991.680
→ hasil dari 8!! - 6!! adalah 366
→ hasil dari 7! × 5 adalah 604.800
→ hasil dari 4!! ÷ 3!! adalah 2,6
