Answer 1

Resposta:

$( - 7) \times ( + 11) \times ( - 2) = \\ ( - 77) \times ( - 2) = \\ ( + 154)ou \: 154$

$( - 9) \times ( - 5) \times ( - 8) = \\ ( + 45) \times ( - 8) = \\ ( - 360)ou - 360$

$( - 12) \times ( - 6) \times ( + 3) = \\ ( + 72) \times ( - 3) = \\ ( - 216)ou - 216$

$( - 8) \times ( + 10) \times ( + 7) \times ( + 2) = \\ ( - 80) \times ( + 14) = \\ ( - 1.120)ou - 1.120$

$( - 8) \times ( + 6) \times 0 \times ( - 11) = \\ ( - 48) \times 0 = \\ 0$

$( + 13) \times ( + 9) \times ( + 10) = \\ ( + 117) \times ( + 10) = \\ ( + 1.170)ou1.170$

$( - 9) \times ( + 12) \times ( - 2) = \\ ( - 108) \times ( - 2) = \\ ( + 216)ou216$

$( - 7) \times ( - 10) \times ( - 5) = \\ ( + 70) \times ( - 5) \\ ( - 350)ou - 350$

$( - 20) \times ( - 2) \times ( + 6) \times ( + 4) \times ( - 1) = \\ ( + 40) \times ( + 24) \times ( - 1) = \\ ( + 960) \times ( - 1) = \\ ( - 960)ou - 960$

espero ter ajudado
