Question

$3 \times ( - {4) }^{2} +( - 5) \times ( + 6)$
${5}^{0} + 8 \div ( - {2}^3} - 6 \times ( - {1}^{5} )$

​

Answer 1

Explicação passo-a-passo:

1)

$3 \times {( - 4}^{2} ) + ( - 5) \times ( + 6) = \\ 3 \times ( - 16) + ( - 30) = \\ - 48 - 30 = - 78$

2)

${5}^{0} + 8 \div ( { - 2}^{3}) - 6 \times ( { - 1}^{5} ) = \\ 1 + 8 \div ( - 8) - 6 \times (- 1) = \\ 1 + ( - 1) + 6 = \\ 1 - 1 + 6 = 6$
