Answer 1

6 × 5! = 720

7! = 5.040

5 + 3 - 2 × 6 = -4

Penjelasan dengan langkah-langkah :

6 × 5! → 6!

= 6 × 5 × 4 × 3 × 2 × 1

= 30 × 4 × 3 × 2 × 1

= 120 × 3 × 2 × 1

= 360 × 2 × 1

= 720 × 1

= 720

7!

= 7 × 6 × 5 × 4 × 3 × 2 × 1

= 42 × 5 × 4 × 3 × 2 × 1

= 210 × 4 × 3 × 2 × 1

= 840 × 3 × 2 × 1

= 2.520 × 2 × 1

= 5.040 × 1

= 5.040

–––

5 + 3 - 2 × 6

= 5 + 3 - (2 × 6)

= 5 + 3 - (2 + 2 + 2 + 2 + 2 + 2)

= 5 + 3 - (4 + 2 + 2 + 2 + 2)

= 5 + 3 - (6 + 2 + 2 + 2)

= 5 + 3 - (8 + 2 + 2)

= 5 + 3 - (10 + 2)

= 5 + 3 - 12

= 8 - 12

= -4
