Question

Resolvam pra mim essas expressões numéricas, pfvv


7-3.4+16:8=

-12:4+3.7+15=3=

17.2-3.4+18:2=

5.[8+(3-4.7)-5.3]=

{4+[27:9+(12:4-5)-3]-2.60}=

Answer 1

Resposta:

7-3.4+16:8= 7

-12:4+3.7+15÷3= 23

17.2-3.4+18:2= 31

5.[8+(3-4.7)-5.3]= 90

{4+[27:9+(12:4-5)-3]-2.60}= - 118

Explicação passo-a-passo:

7-3.4+16:8=

7 - 12 + 2

5 + 2 = 7

-12:4+3.7+15÷3=

-3 + 21 + 5

18 + 5 = 23

17.2-3.4+18:2=

34 - 12 + 9

22 + 9 = 31

5.[8+(3-4.7)-5.3]=

5.[8+(3-28)-5.3]

5 . [8 + 25 - 5 . 3]

5 . [8 + 25 - 15]

5 . [ 33 - 15 ]

5 . 18 = 90

{4+[27:9+(12:4-5)-3]-2.60}=

{4+[27:9+(3-5)-3]-2.60}

{4+[27:9+(-2)-3]-2.60}

{4+[3 - 2 - 3]-120}

{4 + [-2] - 120}

{4 - 2 - 120}

2 - 120 = -118
