.......


............

• Peny ;

= 3! × 5! + 4! - 25 × 2 + 15

= (3.2.1) × (5.4.3.2.1) + (4.3.2.1) - 25 × 2 + 15

= (6.1) × (20.3.2.1) + (12.2.1) - 25 × 2 + 15

= 6 × (60.2.1) + (24.1) - 25 × 2 + 15

= 6 × 120 + 24 - 25 × 2 + 15

= ( 6 × 120 ) + 24 - ( 25 × 2 ) + 15

= 720 + 24 - 50 + 15

= 744 - 50 + 15

= 694 + 15

= 709 ✔️

Penjelasan dengan langkah-langkah:

____________________________

3!

= 3 × 2 × 1

= 6 × 1

= 6

____________________________

5!

= 5 × 4 × 3 × 2 × 1

= 20 × 3 × 2 × 1

= 60 × 2 × 1

= 120 × 1

= 120

____________________________

4!

= 4 × 3 × 2 × 1

= 12 × 2 × 1

= 24 × 1

= 24

____________________________

3! × 5! + 4! - 25 × 2 + 15

= 6 × 120 + 24 - 25 × 2 + 15

= 720 + 24 - 50 + 15

= 744 - 50 + 15

= 759 - 50

= 709
