Question

8-{5+4 [-6+7 ( 5-2 ) ]} =
{7×5[4+2(7-1)]} =
45-{27÷[3.5+2/5) ×6+3/5]}=

Answer 1

Respuesta:

8-{5+4 × [-6+7 × ( 5-2 ) ] } = -57

{ 7 × 5 × [ 4 + 2 × ( 7 - 1 ) ] } = 560

45 - { 27 ÷ [ ( 3.5 +2/5 ) × 6 + 3/5 ] } = 43,875

Explicación paso a paso:

8-{5+4 × [-6+7 × ( 5-2 ) ] } =

8-{5+4 × [-6+7 × ( 3 ) ] } =

8-{5+4 × [-6+21] } =

8-{5+4 × [15] }

8-{5+60}

8-65

-57

{ 7 × 5 × [ 4 + 2 × ( 7 - 1 ) ] } =

{ 7 × 5 × [ 4 + 2 × ( 6 ) ] } =

{ 7 × 5 × [ 4 + 12 ] } =

{ 7 × 5 × [ 16 ] } =

{ 7 × 80 } =

560

45 - { 27 ÷ [ ( 3.5 +2/5 ) × 6 + 3/5 ] } =

45 - { 27 ÷ [ ( 3.5 +2/5 ) × 6 + 3/5 ] } =

45 - { 27 ÷ [ ( 19,5/5 ) × 6 + 3/5 ] } =

45 - { 27 ÷ [ 117/5 + 3/5 ] } =

45 - { 27 ÷ [ 120/5 ] } =

45 - { 27 ÷ [ 24 ] } =

45 - { 1,125 } =

43.875
