Answer 1

Respuesta:

A= 15.62     B= 67.82     c=18.76    D=19      E=24     F=57

Explicación paso a paso:

A) =[0.5+(3.2-1)-0.5](11.2-4.1)]

[0.5+2.2-0.5]7.1

[2.2]7.1

15.62

B)=0.3 + (9.86−1.42) [(5) + 10(5.3− 5)]

0.3+8.44[5+10(0.3)]

0.3+8.44[5+3]

0.3+8.44[8]

0.3+67.52= 67.82

C)=34− {2.5[12(8-6) −18] + 0.6(0.4)}

34-{2.5[24-18]+0.24}

34-{15+0.24}

34-15.24=18.76

D)=34 − 2.5[12(8-6) −18] + 0.6(0.4)

34-2.5[24-18]+0.24

34-15.24+0.24

19

E)=-6 + {3[4+2(7-4)]}

-6+{3[4+6]}

-6+{3[10]}

-6+[30]

-6+30

24

F)=8- {5+4[-6+7(5-2)]}

8-{5+4[-6+7(3)]}

8-{5+4[-6+21}}

8-{5+4[15]}

8-{5+60}

8-65

57
