selamat mengerjakan :)
Jawaban:
1. 7! - 6! = 4.320
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
6! = 6 × 5 × 4 × 3 × 2 × 1
= 30 × 4 × 3 × 2 × 1
= 120 × 3 × 2 × 1
= 360 × 2 × 1
= 720 × 1
= 720
Jadi, 7! - 6! = 5.040 - 720 = 4.320
2. 3³ = 3 × 3 × 3
= 9 × 3
= 27

Jwb :
7! - 6! =
= 7! - 6!
= 7 × 6 × 5 × 4 × 3 × 2 × 1 - 6!
= 42 × 5 × 4 × 3 × 2 × 1 - 6!
= 210 × 4 × 3 × 2 × 1 - 6!
= 840 × 3 × 2 × 1 - 6!
= 2.520 × 2 × 1 - 6!
= 5.040 × 1 - 6!
= 5.040 - 6!
= 5.040 - 6 × 5 × 4 × 3 × 2 × 1
= 5.040 - 30 × 4 × 3 × 2 × 1
= 5.040 - 120 × 3 × 2 × 1
= 5.040 - 360 × 2 × 1
= 5.040 - 720 × 1
= 5.040 - 720
= 4.320
______
3³ =
= 3 × 3 × 3
= 3 + 3 + 3 × 3
= 6 + 3 × 3
= 9 × 3
= 9 + 9 + 9
= 18 + 9
= 27
