Question

Calcule o valor das expressões numéricas:
 3 . { -1 + 3 [ - 5 + 4 (1 – 1/2 ) – 1 ] -3 } = 

 { 40 + [ ( 12 . 2 – 4 ) – ( 5 . 4 – 12/3 ) + 6 + 3 ] + 7 . 5 } =

 1/6 ÷ { 2 . [ ( 2 + 1/2 ) ÷ (2 – 1/2) + (1/4 ÷ 1/2) . ( 1/3 .2 – 1/3 )] + 5 } =

 4/3+[4/6÷(1/3+5/3–1)–1/3]+1/5.3/4 =

 2 . { 5 . [ 3 - ( 6 – 10) + 2 ] - 5 } – 5 =

Answer 1

Resposta: 3 . { -1 + 3 [ - 5 + 4 (1 – 1/2 ) – 1 ] -3 } = 

 { 40 + [ ( 12 . 2 – 4 ) – ( 5 . 4 – 12/3 ) + 6 + 3 ] + 7 . 5 } =

Explicação:

 4/3+[4/6÷(1/3+5/3–1)–1/3]+1/5.3/4 =

 2 . { 5 . [ 3 - ( 6 – 10) + 2 ] - 5 } – 5 =
