6!! - 4!! =



Note : Panen:-:​

Jawaban:

[tex] \tiny n!!=n \times (n - 2) \cdots \times 4 \times 2∣n \in genap \: \: \: \: \: \: \\ \tiny=n \times (n - 2) \cdots \times 3 \times 1∣n \in ganjil[/tex]

8!! + 4!!

= (8 × 6 × 4 × 2) + (4 × 2)

= (48 × 8) + 8

= 384 + 8

= 392

..

6!! - 4!!

= (6×4×2) - (4×2)

= (24×2) - 8

= 48 - 8

= 40

Nomor.1

= 8!! + 4!!

= (8 × 6 × 4 × 2 × 1) + (4 × 2 × 1)

= 384 + 8

= 392

Nomor.2

= 6!! - 4!!

= (6 × 4 × 2 × 1) - (4 × 2 × 1)

= 48 - 8

= 40
