Question

Resolva a expressão:
(-1/2)² x (+3/2) - (+2/3)³ : (-1/27)

Answer 1

+ 1/4  x (+3/2) - 8/27:(-1/27)
3/12 - ( 8/27.(-27/8)
3/12- 1
MMC = 12
3/12/1 - 1/1/12
3/12 - 12/12
-9/12 = - 3/4

Answer 2

1/4 x 3/2 - (+ 8/27) : (-1/27)=
3/8         - (+8/27) x (-27/1) =
3/8     - (-216/27)=
3/8 + 8
MMC 8
3 + 64/8=
Resposta final: 67/8
