Question

qual e a resposta das expressões numericas: 50+{10-2×[(6+4÷2)(10-3]} e 180÷{10+2×[20-45÷(13-2×5)]}?

Answer 1

50 + {10 -2 x [(6 + 4 ÷ 2) (10 - 3 ]}

50 + {10 - 2 x[(6 + 2) (7)]}

50 + {10 - 2 x[(8) (7)]}

50 + {10 - 2 x [8 x 7]}

50 + {10 - 2 x 56}

50 + {10 - 112}

50 + {- 112}

50 - 112

-62

-----------------------------------------

180 ÷ {10 + 2 x [20 - 45 ÷ (13 - 2 x 5)]}

180 ÷ {10 + 2 x [20 - 45 ÷ (13 - 10)]}

180 ÷ {10 + 2 x [20 - 45 ÷ 3]}

180 ÷ {10 + 2 x [20 - 15]}

180 ÷ {10 + 2 x 5}

180 ÷ {10 + 10}

180 ÷ 20
