Q.


1.) 12! - 14 = ...

2.) 12!! - 14 = ...

3.) 12! + 14 = ...

4.) 12!! + 14 = ...​

Penjelasan dengan langkah-langkah:

Jawab (1)

• 12! - 14
• = (12.11.10.9.8.7.6.5.4.3.2.1) - 14
• = 479.001.600 - 14
• = 479.001.586

________

Jawab (2)

• 12!! - 14
• = (12 × 10 × 8 × 6 × 4 × 2) - 14
• = 46.080 - 14
• = 46.066

________

Jawab (3)

• 12! + 14
• = (12.11.10.9.8.7.6.5.4.3.2.1) + 14
• = 479.001.600 + 14
• = 479.001.614

________

Jawab (4)

• 12!! + 14
• = (12.10.8.6.4.2) + 14
• = 46.080 + 14
• = 46.094

Penjelasan dengan langkah-langkah:

1.) 12! - 14

= 12x11x10x9x8x7x6x5x4x3x2x1 – 14

= 132 x 90 x 56 x 30 x 24 – 14

= 11.880 x 1.680 x 24 – 14

= 19.958.400 x 24 – 14

= 479.001.600 – 14

= 479.001.586

2.) 12!! - 14

= 12x10x8x6x4x2 – 14

= 120 x 48 x 8 – 14

= 5.760 x 8 – 14

= 46.080 – 14

= 46.066

3) 12! + 14

= 12x11x10x9x8x7x6x5x4x3x2x1 + 14

= 132 x 90 x 56 x 30 x 24 + 14

= 11.880 x 1.680 x 24 + 14

= 19.958.400 x 24 + 14

= 479.001.600 + 14

= 479.001.614

4.) 12!! + 14

= 12x10x8x6x4x2 + 14

= 120 x 48 x 8 + 14

= 5.760 x 8 + 14

= 46.080 + 14

= 46.094
