Question

necesito ayuda! necesito repuesta de este cuadro! ​

Answer 1

Respuesta:

Explicación paso a paso:

A.B + C.D

1.1 2.5 + 1.7 = 10 + 7 = +17

1.2 -3.4 + (-1).5 = -12 - 5 = - 17

1.3 -6.-3 + 3.(-4) = +18 - 12 = +6

1.4 4.-2 + (-2).20 = -8 - 40 = 48

A.(B+C).D

1.1 2.(5 + 1).7 = 2.6.7 = 12.7 = 84

1.2 -3.(4 + -1).5 = -3.3.5= -9.5 = -45

1.3 -6.(-3 + 3).-4 = -6.0.-4 = 0

1.4 4.(-2 + (-2)).20 = 4.-4.20 = -16.20 = 320

A-(B:C).D

1.1 2 -(5:1).7 = 2 - 5.7 = 2 - 35 = 33

1.2 -3 -(4:-1).5 = -3 - (-4).5 = -3 + 4.5 = -3 + 20 = 17

1.3 -6-(-3:3).-4 = -6 - (-1).-4 = -6 + 1.-4 = -6 - 4 = -10

1.4 4-(-2:-2).20 = 4 - (+1).20 = 4 -1.20 = 4 - 20 = -16

Answer 2

Respuesta:

1

a.b+c.d --> -6.-3 + 3.(-4) = +18 - 12 = +6

a.(b+c).d --> 2.(5+1).7 --> 2.6.7 --> 84

a-(b:c).d --> 2-(5:1).7 --> 2-5.7 --> 33

2

a.b+c.d --> -3.4 + (-1).5 = -12 - 5 = - 17

a.(b+c).d --> -3.(4 + -1).5 = -3.3.5= -9.5 = -45

a-(b:c).d --> -3 -(4:-1).5 = -3 - (-4).5 = -3 + 4.5 = -3 + 20 = 17

3

a.b+c.d --> -6.(-3)+3.(-4) --> 18-12 --> 6

a.(b+c).d --> -6.(-3 + 3).-4 = -6.0.-4 = 0

a-(b:c).d --> -6-(-3:3).-4 = -6 - (-1).-4 = -6 + 1.-4 = -6 - 4 = -10

4

a.b+c.d --> 4.-2 + (-2).20 = -8 - 40 = 48

a.(b+c).d --> 4.(-2 + (-2)).20 = 4.-4.20 = -16.20 = 320

a-(b:c).d --> 4-(-2:-2).20 = 4 - (+1).20 = 4 -1.20 = 4 - 20 = -16
