Penjelasan dengan langkah-langkah:
1.) 20!! - (-15!!)
- = ((20 × 18)) × ((16 × 14)) × ((12 × 10)) × ((8 × 6)) × ((4 × 2))
= ((360 × 224)) × ((120 × 48)) × 8
= (80.640 × 5.760) × 8
= 464.486.400 × 8
= 3.715.891.200
- = ((15×13)) × ((11×9)) × ((7×5)) × ((3×1))
= ((195 × 99)) × ((35 × 3))
= 19.305 × 105
= 2.027.025
hasil
= (3.715.891.200)) - ((-2.027.025)
= 3.715.891.200 + 2.027.025
= 3.717.918.225
2.) 10!
