7!! + 8³ - 6 ÷ 2
(7 × 5 × 3) + (8 × 8 × 8) - 6 ÷ 2
(35 × 3) + (64 × 8) - 6 ÷ 2
105 + 512 - 6 ÷ 2
105 + 512 - (6 ÷ 2)
105 + 512 - 3

= 614
Contoh bilangan faktorial :
1! = 1
2! = 2 × 1 = 2
3! = 3 × 2 × 1 = 6
4! = 4 × 3 × 2 × 1 = 24
5! = 5 × 4 × 3 × 2 × 1 = 120
1!! = 1
2!! = 2
3!! = 3 × 1 = 3
4!! = 4 × 2 = 8
5!! = 5 × 3 × 1 = 15
6!! = 6 × 4 × 2 = 48
7!! = 7 × 5 × 3 = 105
Penjelasan dengan langkah-langkah:
7!!
= 7x5x3x1
= 35x3x1
= 105
8³
= 8x8x8
= 64x8
= 512
6 ÷ 2
= 3
7!! + 8³ - 3
= 105 + 512 - 3
= 617 - 3
