    B 4 Correct Answer Incorrect Answer
    C 3 Correct Answer Incorrect Answer
    D 2 Correct Answer Incorrect Answer

    Solution

    Ax 2  (x + 2) + 8 + 36x = (2 + 3x) 3

    Ax 3  + 2Ax 2  + 8 + 36x = 8 + 27x 3  + 36x + 54x 2

    Ax 3  + 2Ax 2  = 27x 3  + 54x 2

    After comparing: A = 27

    Now, 3 √A

    =  3 √27 = 3
