Explicação passo-a-passo:

$\tt \: resposta \: correta \: será : \\ \\ \alpha )( + 9) ^{2} + {( - 6)}^{3} - {( - 2)}^{3} = - 127 \\ \\ \beta ) {( - 1)}^{2} \times {( + 5)}^{3} = 125 \\ \\ c)1 - ( + 12) + ( - 3) - ( - 2) = - 12 \\ \\ d) {( - 9)}^{2} \div ( - 9) \times 9 - ( + 3) = - 84 \\ \\ e) - 45 + ( - 5) - ( + 30) = - 80 \\ \\ f) {( - 6)}^{3} - ( - 25) = - 191$
