a] 7.3+(6+2.(2³:4+3.2)-7.√1)+9:3 =
7.3 + (6 + 2. (8:4 + 3.2) - 7.√1) + 9:3 =
7.3 + (6 + 2.(2+3.2) – 7.√1) + 9:3 =
7.3 + (6 + 2. (2 + 6) – 7.√1) + 9:3 =
7.3 + (6 + 2. (8) – 7.√1) + 9:3 =
7.3 + (6 + 16 – 7.√1) + 9:3 =
7.3 + (6 + 16 – 7.1) + 9:3 =
7.3 + (6 + 16 – 7) + 9:3 =
7.3 + 15 + 9:3 =
21 + 15 + 3 = 39 Resultado
