Q. ( Ngepasin Poin)

= 5! + 3!

= (5.4.3.2.1) + (3.2.1)

= 120 + 6

= 126

____________________

= 6! – 4!

= (6.5.4.3.2.1) – (4.3.2.1)

= 720 – 24

= 696

5! + 3! = (5 × 4 × 3 × 2 × 1) + (3 × 2 × 1)

= (20 × 3 × 2 × 1) + (6 × 1)

= (60 × 2 × 1) + 6

= (120 × 1) + 6

= 120 + 6

= 126

6! – 4! = (6 × 5 × 4 × 3 × 2 × 1) – (4 × 3 × 2 × 1)

= (30 × 4 × 3 × 2 × 1) – (12 × 2 × 1)

= (120 × 3 × 2 × 1) – (24 × 1)

= (360 × 2 × 1) – 24

= (720 × 1) – 24

= 720 – 24

= 696
