Answer 1

Resposta:

Explicação passo a passo:

3³- 2 ×[3² +(4² -5 )×3] =

3³ - 2 X { 3² + ( 16 - 5 ) X 3 } =

3³ - 2 X { 3² + 11 X 3 } =

3³ - 2 X { 9 + 33 } =

3³ - 2 X 42 =

27 - 84 =

= 57

40+{3+[(2³+12)+(13+2²+3)]+5} =

40+{3+[ 20+20]+5} =

40+{3+40+5} =

40 + 48 =

= 88

{2⁵-[5+(3+7-4)}÷5+3²×2-(8²-60)×5 =

{2⁵-[5+(3+7-4)}÷5+3²×2-4×5 =

{2⁵-[5+(3+7-4)}÷7 =

{2⁵-[5+6}÷7 =

2⁵- 11 ÷ 7 =

32 - 157 =

= 125

{[(2³×2³+3)÷7+(3+15÷5)×3]×2-(19-7)÷6}×2²+3​ =

{[(2³×2³+3)÷7+(3+15÷5)×3]×2-12÷6}×2²+3​ =

{[67÷7+ 6×3]×2 - 2 }×2²+3​ =

{[9,57 + 18]×2 - 2 }×2²+3​ =

{27,57×2 - 2 }×2²+3​ =

55,12 X 4 + 3 =

220,48 + 3 =

= 220,51
