2.
2x(3+4)-3×(7-4) + (1/3-3/2)-((2/5+1/3)-2)

3.
[9×(7-3)-2×(7+5)] ÷ ((5-8)×(2-3) +4)​

Answer 1

Respuesta:

1.=14

2.=239/24

3.=9.71

Explicación paso a paso:

1.

2×(5+3)-3×(5-2) +3× ((5-8)×(2-3) +4)

2×8-3×3+3×(3×1+4)

2×8-3×3+3×7

16-9+21

16-30=14

2.

2×(3+4)-3×(7-4) + (1/3-3/2)-((2/5+1/3)-2)

2×7-3×3+7/6-(3/8-2)

2×7-3×3+7/6-1/8

2×7-3×3+25/24

2×7-3×97/24

14-3×97/8=239/24

3.

[9×(7-3)-2×(7+5)] ÷ ((5-8)×(2-3) +4)​

[9×4-2×2]÷(3×1+4)

[36-2×2]÷7

[34×2]÷7

68÷7=9.71
