Berikut ini adalah pertanyaan dari Zaidan667 pada mata pelajaran Matematika untuk jenjang Sekolah Menengah Atas
1. 9!! × 6!!! =
2. 6! + 7! × 3! =
Jawaban dan Penjelasan
Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.
SOAL . 1
= 9!! × 6!!!
= (9 × 7 × 5 × 3 × 1) × 6!!!
= (63 × 5 × 3 × 1) × 6!!!
= (315 × 3 × 1) × 6!!!
= (945 × 1) × 6!!!
= 945 × 6!!!
= 945 × (6 × 3 × 1)
= 945 × (18 × 1)
= 945 × 18
= 17.010
SOAL . 2
= 6! + 7! × 3!
= (6 × 5 × 4 × 3 × 2 × 1) + 7! × 3!
= (30 × 4 × 3 × 2 × 1) + 7! × 3!
= (120 × 3 × 2 × 1) + 7! × 3!
= (360 × 2 × 1) + 7! × 3!
= (720 × 1) + 7! × 3!
= 720 + 7! × 3!
= 720 + (7 × 6 × 5 × 4 × 3 × 2 × 1) × 3!
= 720 + (42 × 5 × 4 × 3 × 2 × 1) × 3!
= 720 + (210 × 4 × 3 × 2 × 1) × 3!
= 720 + (840 × 3 × 2 × 1) × 3!
= 720 + (2.520 × 2 × 1) × 3!
= 720 + (5.040 × 1) × 3!
= 720 + 5.040 × 3!
= 720 + 5.040 × (3 × 2 × 1)
= 720 + 5.040 × (6 × 1)
= 720 + 5.040 × 6
= 720 + 30.240
= 30.960
