me ajudem ai pfvr, é trabalho​

Answer 1

{-20+[√144×(-5)+(-3)³÷(-9) ] }

{-20+[12×(-5)+(-27)÷(-9)]}

{-20+[-60+3]

-20-57

=-77

Answer 2

Resposta:

{-20 + [$\sqrt{144}$ . (-5) + (-3)³ : (-9)]} =

{-20 + [$\sqrt{144}$ . -5 + 27 : -9]} =

{-20 + [$\sqrt{144}$ . -5 + (-3)]} =

{-20 + [$\sqrt{144}$ . -5 - 3]} =

{-20 + [$\sqrt{144}$ . -8]} =

{-20 + [ 12 . -8]} =

{-20 + (-96)} =

{-20 -96} =

-116
