Question

me ayudan con los ejercicios porfa y el procedimiento

Answer 1

Explicación paso a paso:

1) está resuelto

2) 27 + 3 - 45 ÷ 5 + 16

= 30 - 9 + 16

= 21 + 16

= 37

3) (2 × 4 +12)(6 - 4)

= (8 + 12)(2)

= (20)(2)

= 40

4) 3 × 9 + (6 + 5 - 3) - 12 ÷ 4

= 27 + ( 11 - 3) - 3

= 27 + 8 - 3

= 27 + 5

= 32

5) está resuelto

6) 440 - [ 30 + 6 (19 - 12)]

= 440 - [ 30 + 6 (7)]

= 440 - [30 + 42]

= 440 - 72

= 368

7) 2 {4 [7 + 4 (5 × 3 - 9)] - 3 (40 - 8)}

= 2 {4 [7 + 4 (15 - 9)] - 3 (32)}

= 2 {4 [7 + 4 (6)] - 96}

= 2 {4 [7 + 24] - 96}

= 2 {4 [31] - 96}

= 2 {124 - 96}

= 2 {28}

= 56

8) 7 × 3 + [6 + 2 × (2^3 ÷ 4 + 3 × 2) - 7 × 4] + 9 ÷ 3

= 21 + [6 + 2× (8 ÷ 4 + 6) - 28] + 3

= 21 + [6 + 2 × (2 + 6) - 28] + 3

= 21 + [6 + 2 × (8) - 28] + 3

= 21 + [ 6 + 16 - 28] + 3

= 21 + [ - 6] + 3

= 21 - 6 + 3

= 18

9) 96 - {85 - [47 + ( 59 - 39) - 24] + 18} - 26

= 96 - {85 - [47 + (20) - 24] + 18} - 26

= 96 - {85 - [43] + 18 } - 26

= 96 - {60} - 26

= 96 - 86

= 10

10) 39 + {15 - [17 - (29 - 19) + (6 × 3)] - 3^3} - 13

= 39 + { 15 - [17 - (10) + (18)] - 27} - 13

= 39 + {15 - [17 - 10 + 18] - 27} - 13

= 39 + {15 - [25] - 27} - 13

= 39 + {15 - 25 - 27} - 13

= 39 + {- 37} - 13

= 39 - 37 - 13

= - 11
