Porfavor me pueden ayudar

Answer 1

Respuesta:

esta fácil

Explicación paso a paso:

1. (-4 + 6) - [-4 (9 - 3)]

        2 - [-4 (6)]

        2 - -24 = 26

2. 18 + [ 13 + 4 – ( 5 – 7 ) + 6 ]

    18 + 13 + 4 - (-2) + 6

     18 + 25 = 43

3. 15 – [12 – 3 . 4 . (– 5 ) + 10]

   15 - [12 - 3 x -20 + 10]

   15 - [12 - -60 + 10

   15 - [72 + 10]

   15 - 82 = -67

4. 18 – [2 – ( 4 + 5 ) . (– 4 + 9)]

   18 - [2 - 9 (-4 + 9)]

   18 - 2 - 9 x 5

   18 - 2 - 45

   18 - -43 = 61

5. – [13 – ( 12 – 6 )] – [ 3 . (– 6)]

    - [13 - 6] - [3 .(-6)]

    -7 - (-18) = 11

6. ( 5 – 4 . 6 ) . [ 3 – (– 2 ) . 4 . (– 3 )]

    -19 x [3 - (-2) x 4 x (-3)]

    -19 x [3 - (-8) x -3]

    -19 x [3 - 24]

    -19 x -21 = 399

7. [3 – ( 5 + 15 : 3 ) ] : [16 – (– 3 ) . (– 5 )]

      -7 : [16 - (-3) (-5)]

      -7 : 1 = -7

8. – [16 – (8 – 5 . 6)] – (6 – 8 : 2) . (– 7)

   - [16 - (-22)] - 2 .(-7)

   - 38 - (-14) = -24

espero que te ayude suerte en todo...
