Question

Me ajudem só com essa por favor.


5) 60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} =
6) -8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =
7) 3² – {2 + (11 – 15) – [5 + (-3 + 1)] + 8} =
8) [-1 + (2² – 5 · 6)] ÷ (-5 + 2) + 1 =
9) [ – (2³ – 8) · 2 – 24] ÷ [2 ² – (3 + 2)] =
10) {[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 – (19 – 7) ÷ 6} =

Answer 1

Resposta:

5) -6 / 6) 8 / 7) 6 / 8) 13,5 / 9) 24 / 10) 44

Explicação passo-a-passo:

5) 60 ÷ {2 . [ -7 +18 ÷ (-3 +12)]}

60÷{2.[-7+18÷9]}

60÷{2.[-7+2]}

60÷{2.(-5)}

60÷{-10}

-6

6) -8+{5+[(8-12)+(13+12)]-10}

-8+{5+[-4+25]-10}

-8+{5+21-10}

-8+{16}

-8+16= 8

7) 3²-{2+(11-15)-[5+(-3+1)]+8}

9- {2+(-4)-[5+(-2)]+8}

9-{-2-[3]+8}

9-{-5+8}

9-3= 6

8) [-1 + (2² – 5 · 6)] ÷ (-5 + 2) + 1

[-1+(4-30)]÷(-3)+1

[-1+(-26)] ÷ (-2)

[-27] ÷ (-2)

-27÷(-2) = 13,5

9) [ – (2³ – 8) · 2 – 24] ÷ [2 ² – (3 + 2)]

[ - 0.2-24]÷ [4-5]

[-0-24]÷[-1]

-24÷[-1]= 24

10) {[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 – (19 – 7) ÷ 6}

{[35÷7+6.3].2-12÷6}

{23.2-12÷6}

{46-2}= 44
