Jawaban :

(20 - 10)! - (5 + 3)! =

= 10! - 8!

--

10! =

= 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 90 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 720 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 5.040 × 6 × 5 × 4 × 3 × 2 × 1

= 30.240 × 5 × 4 × 3 × 2 × 1

= 151.200 × 4 × 3 × 2 × 1

= 604.800 × 3 × 2 × 1

= 1.814.400 × 2 × 1

= 3.628.800 × 1

= 3.628.800

--

8! =

= 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 56 × 6 × 5 × 4 × 3 × 2 × 1

= 336 × 5 × 4 × 3 × 2 × 1

= 1.680 × 4 × 3 × 2 × 1

= 6.720 × 3 × 2 × 1

= 20.160 × 2 × 1

= 40.320 × 1

= 40.320

---

10! - 8! =

= 10! - 8!

= (10.9.8.7.6.5.4.3.2.1) - (8.7.6.5.4.3.2.1)

= 3.628.800 - 40.320

= 3.588.480

___________________________

Kesimpulan :

• Hasil dari (20 - 10)! - (5 + 3)! adalah 10! - 8!/3.588.480
