Penjelasan dengan langkah-langkah:
= 7! + 5!² - 6!! × 2³
= (7.6.5.4.3.2.1) + (5.4.3.2.1)² - (6.4.2) × (2.2.2)
= (42.20.6) + (20.6)² - (24.2) × (4.2)
= (42.120) + 120² - 48 × 8
= 5.040 + 14.400 - 384
= 19.440 - 384
= 19.056

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
___________________________________________ 5!²
= (5 × 4 × 3 × 2 × 1)²
= (20 × 3 × 2 × 1)²
= (60 × 2 × 1)²
= (120 × 1)²
= (120)²
= 120²
= 14.400
6!!
