• 7! - 5!

= ( 7 × 6 × 5 × 4 × 3 × 2 ) - ( 5 × 4 × 3 × 2 )

= ( 42 × 5 × 4 × 3 × 2 ) - ( 20 × 3 × 2 )

= ( 210 × 4 × 3 × 2 ) - ( 60 × 2 )

= ( 840 × 3 × 2 ) - 120

= ( 2.520 × 2 ) - 120

= 5.040 - 120

= 4.920

• 23²

= 23 × 23

= 529

Penyelesaian :

7! - 5!

= (7×6×5×4×3×2×1) - (5×4×3×2×1)

= (42×5×4×3×2×1) - (20×3×2×1)

= (210 × 4 × 3 × 2 × 1) - (60 × 2 × 1)

= (840 × 3 × 2 × 1) - (120 × 1)

= (2.520 × 2 × 1) - 120

= 5.040 - 120

= 4.920

23²

= 23 × 23

= 529
