Answer 1

Răspuns:

Explicație pas cu pas:

50 × 150 × 4 = 150 × ( 50×4) = 150 × 200 = 30 000 → primul mod

50 × 150 × 4 = 50 × ( 150×4) = 50 × 600 = 30 000 → al doilea mod

30 × 137 × 20 = ( 30×137) × 20 = 4 110 × 20 = 82 200 → primul mod

30 ×137 × 20 = 137 × (30×20) = 137×600 = 82 200 → al doilea mod
