Penjelasan dengan langkah-langkah:

7! - 8!

= (7 × 6 × 5 × 4 × 3 × 2 × 1) - (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)

= (42 × 20 × 6) - (56 × 30 × 12 × 2)

= (840 × 6) - (1.680 × 24)

= 5.040 - 40.320

Answer 2

Jawaban:

• 7! = 5.040

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

• 8! = 40.320

8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 56 × 6 × 5 × 4 × 3 × 2 × 1

= 336 × 5 × 4 × 3 × 2 × 1

= 1.680 × 4 × 3 × 2 × 1

= 6.720 × 3 × 2 × 1

= 20.160 × 2 × 1

= 40.320 × 1

= 40.320

• 5.040 - 40.320
• = -35.280
