    Answer: (1) 0.81

    Explanation:-
    {0.9[2.3 – 3.2 – (7.1 – 5.4 – 3.5)]}
    = {0.9[ 2.3 – 3.2 –  (7.1 – 8.9)]}
    = {0.9 [2.3 – 3.2 – (- 1.8)]}
    = {0.9 [ 2.3 – 3.2 + 1.8]}
    = {0.9 [4.1 – 3.2]}
    = {0.9 [0.9]}
    = 0.9 x 0.9
    = 0.81

    Then, the value of {0.9[2.3 – 3.2 – (7.1 – 5.4 – 3.5)]} is 0.81.

    Hence, the answer is (1) 0.81.
