- 3! - 4!
- 5! × 6!
- 7! ÷ 8!
- 9! + 10!
PEMBAHASAN
- 1! + 2!
- = 1 + ( 2 × 1 )
- = 1 + 2
- = 3
___________________________
- 3! - 4!
- = ( 3 × 2 × 1 ) - ( 4 × 3 × 2 × 1 )
- = ( 6 × 1 ) - ( 12 × 2 × 1 )
- = 6 - ( 24 × 1 )
- = 6 - 24
- = -18
___________________________
- 5! × 6!
- = ( 5 × 4 × 3 × 2 × 1 ) × ( 6 × 5 × 4 × 3 × 2 × 1 )
- = ( 20 × 3 × 2 × 1 ) × ( 30 × 4 × 3 × 2 × 1 )
- = ( 60 × 2 × 1 ) × ( 120 × 3 × 2 × 1 )
- = ( 120 × 1 ) × ( 360 × 2 × 1 )
- = 120 × ( 720 × 1 )
- = 120 × 720
- = 86.400
____________________________
- 7! ÷ 8!
- = ( 7 × 6 × 5 × 4 × 3 × 2 × 1 ) ÷ ( 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 )
- = 5.040 ÷ 40.320
- = 0,125
_____________________________
- 9! + 10!
- = ( 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 ) + ( 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 )
- = 362.880 + 3.628.800
- = 3.991.680

1. 1! + 2! = 1 + (2 x 1) = 1 + 2 = 3
2. 3! - 4! = (3 x 2 x 1) - (4 x 3 x 2 x 1) = 6 + 24 = -18
3. 5! × 6! = (5 x 4 x 3 x 2 x 1) × (6 x 5 x 4 x 3 x 2 x 1) = 120 × 720 = 86.400
4. 7! ÷ 8! = (7 x 6 x 5 x 4 x 3 x 2 x 1) ÷ (8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 5.040 ÷ 40.320 = 0,125
5. 9! + 10! = (9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) + (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 362.880 + 3.628.800 = 3.991.680
Bilangan yang ada tanda seru (!) setelah angka disebut faktorial. Contoh faktorial adalah 6! (6 faktorial), cara mencari angka asli dari 6! adalah 6 x 5 x 4 x 3 x 2 x 1
Maaf kalo salah
Kalo benar jadikan jawaban tercerdas
Semoga bermanfaat
