Resposta:

55/7.

Explicação passo a passo:

(√49/4 + 7/4) x 4/3 + (3/2)² : [(4/3 - √25/36) : 2/3] =

(7/2 + 7/4) x 4/3 + 9/4 : [(4/3 - 5/6) : 2/3] =

(14/4 + 7/4) x 4/3 + 9/4 : [8/6 - 5/6) : 2/3] =

21/4 x 4/3 + 9/4 : [3/6 : 2/3] =

84/12 + 9/4 : [3/6 x 3/2] =

7  + 9/14 : 9/12 =

7 + 9/14 x 12/9 =

7 + 108/126 =

7 + 6/7 =

49/7 + 6/7 =

55/7.
