Answer 1

Resposta:

Explicação passo a passo:

A) (33 + 3 . 7) : {4 . [13 – (32 . 2 + 10)]} (33+21):{4.[13-(64+10)]} 54:{4.[13-74]} 54:{4.[-64]} 54:{-256} 54/-256:2 27/-128 ou -27/128

B) { [ (8 . 4 + 3) ÷ 7 + (3 + 15 ÷ 5) . 3] . 2 – (19 – 7) ÷ 6 } . 2 + 12 {[(32+3):7+(3+3).3].2-12:6}.2+12 {[35:7+6.3].2-2}.2+12 {[5+18].2-2].2+12 {23.2-2].2+12 {46-2].2+12 44.2+12 88+12 100

C) 15 – { -3 + [(5 – 6)² . (9 -8 ) ² + 1]} 15-{-3+[(-1)².(1)²+1]} 15-{-3+[1.1+1]} 15-{-3+[1+1]} 15-{-3+2} 15-{-1} 15+1 16

D) 4 – {(-2)² . (-3) – [ -11 + (-3) . (-4)] – (-1)} 4-{4.(-3)-[-11+12]+1} 4-{-12-[1]+1} 4-{-12-1+1} 4-{-12} 4+12 16
