Jawaban:
5.760
Penjelasan dengan langkah-langkah:
6! + 7! = 6! ( 6 × 5 × 4 × 3 × 2 × 1 ) = 720
7! ( 7 × 6 × 5 × 4 × 3 × 2 × 1 ) = 5.040
= 5.040 + 720 = 5.760
10! - 7! = 10! ( 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 ) = 3.628.800
7! ( 7 × 6 × 5 × 4 × 3 × 2 × 1 ) = 5.040
3.628.800 - 5.040 = 3.623.760
Jawaban:
6! = 6 × 5 × 4 × 3 × 2 × 1
= 30 × 4 × 3 × 2 × 1
= 120 × 3 × 2 × 1
= 360 × 2 × 1
= 720
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
6! + 7!
= 720 + 5.040
= 5.760
10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 90 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 720 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 5.040 × 6 × 5 × 4 × 3 × 2 × 1
= 30.240 × 5 × 4 × 3 × 2 × 1
= 151.200 × 4 × 3 × 2 × 1
= 604.800 × 3 × 2 × 1
= 1.814.400 × 2 × 1
= 3.628.800 × 1
= 3.628.800
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
10! - 7!
= 3.628.800 - 5.040
= 3.623.760
