Answer 1

Respuesta:

1 ( - 6 + 10 ) - ( - 8 x 7 ) = 72

2 [ - 15 + ( 4 x - 5 ) ] + 9 =14

3 ( - 10 + 15 ) - ( - 7 - 20 ) = 32

4 [ ( - 8 - 10 ) x ( 4 x - 8 ) ] - 10 =566

5 [ ( - 7 - 6 ) x ( - 4 x 2 ) ] - ( - 3 + 1 )

[( -12) x (-8)] - (-3 + 1)

[(+ 18) x (-32)] -10

[+18 x -32] -10

[ -576]-10

-576-10=  566

Explicación paso a paso:

1° ( - 6 + 10 ) - ( - 8 x 7 ) = 72

(+16) - (-56)

16 + 56 = 72

2° [ - 15 + ( 4 x - 5 ) ] + 9 =14

[- 15+ ( -20)] + 9

[- 15 -20] + 9

[ 5]  + 9

5+9 = 14

3° ( - 10 + 15 ) - ( - 7 - 20 ) = 32

(-5) - ( +27)

-5 -27= +32

4° [ ( - 8 - 10 ) x ( 4 x - 8 ) ] - 10 =566

[(+ 18) x (-32)] -10

[+18 x -32] -10

[ -576]-10

-576-10=  566
