7! + 6! x 3! =.....
Penjelasan dengan langkah-langkah:
7! + 6! x 3!
= (7×6×5×4×3×2) + 6! x 3!
= (42×20×6) + (6×5×4×3×3) × (3×2)
= (840×6) + (30×12×2) × 6
= 5.040 + (360×2) × 6
= 5.040 + 720 × 6
= 5.040 + 4.320
= 9.360
= 7! + 6! × 3!
= ( 7 × 6 × 5 × 4 × 3 × 2 ) + 6! × 3!
= 5.040 + 6! × 3!
= 5.040 + ( 6 × 5 × 4 × 3 × 2 ) × 3!
= 5.040 + 720 × 3!
= 5.040 + 720 × ( 3 × 2 × 1 )
= 5.040 + 720 × 6
= 5.040 + 4.320
= 9.360
