Question

não e pra marca x, sim bota respostas,me ajudem) (f) 8 : 2 + (15 - (4 X 2 + 1)] =
i) 25 - [10 - (2 X 3 + 1)] = g) 9 + [4 + 2 X (6 - 4) + (2 + 5 )] - 8 = (J) 180 : {10 + 2 X [20 - 45 : (13 - 2 X 5]}
(H) 50 + {10 - 2 X [( 6 + 4 : 2) - 10- 3)]} =

Answer 1

8 ÷ 2 + [15 - (4 x 2 + 1)]
4 + [15 - (8 + 1)]
4 + [15 - 9]
4 + 6
10

25 - [10 - (2x3 + 1)]
25 - [10 - (6 + 1 )]
25 - [10 - 7]
25 - 3
22

9 + [4 + 2x(6 - 4) + (2 + 5)] - 8
9 + [4 + 2x2 + 7] - 8
9 + [4 + 4 + 7] - 8
9 + [8 + 7] - 8
9 + 15 - 8
24 - 8

180 ÷ {10 + 2x[20 - 45 ÷ (13-2x5)]}
180 ÷ {10 + 2x[20 - 45 ÷ (13 - 10)]}
180 ÷ {10 + 2x[20 - 45 ÷ 3]}
180 ÷ {10 + 2x[20 - 15]}
180 ÷ {10 + 2x5}
180 ÷ {10 + 10}
180 ÷ 20
160

50 + {10 - 2x[(6 + 4 ÷ 2) -10 - 3}
50 + {10 - 2x[(6 + 2) - 13}
50 + {10 - 2x8 - 13}
50 + {10 - 16 -13}
50 + {-6 -13}
50 + {-19}
50 - 19
