Answer 1

Răspuns:

400:5x[3+2-(60:2-10x3)+3]x2x1=

80·[3+2-(30-30)+3]×2=

80·(3+2-0+3)×2=

80×8×2=

1280

Answer 2

400 : 5 × [ 3 + 2 - (60 : 2 - 10 × 3) + 3] × 2 × 1

= 400 : 5 × [ 3 + 2 - (30 - 30) + 3] × 2

= 400 : 5 × (3 + 2 - 0 + 3) × 2

= 400 : 5 × (5 + 3) × 2

= 400 : 5 × 8 × 2

= 80 × 8 × 2

= 640 × 2

= 1 280
