Penjelasan dengan langkah-langkah:
9! + 10!
= (9.8.7.6.5.4.3.2.1) + (10.9.8.7.6.5.4.3.2.1)
= (72.42.20.6) + (90.56.30.12.2)
= (3.024 × 120) + (5.040 × 720)
= 362.880 + 3.628.800
= 3.991.680
Jawab:
9! + 10! = 3991680
Penjelasan dengan langkah-langkah:
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
= 3024 × 5 × 4 × 3 × 2 × 1
= 15120 × 4 × 3 × 2 × 1
= 60480 × 3 × 2 × 1
= 181440 × 2 × 1
= 362880 × 1
= 362880
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
= 5040 × 6 × 5 × 4 × 3 × 2 × 1
= 30240 × 5 × 4 × 3 × 2 × 1
= 151200 × 4 × 3 × 2 × 1
= 604800 × 3 × 2 × 1
= 1814400 × 2 × 1
= 3628800 × 1
= 3628800
362880 + 3628800 = 3991680
