    (1/b).
    A 58 Correct Answer Incorrect Answer
    B 60 Correct Answer Incorrect Answer
    C 62 Correct Answer Incorrect Answer
    D 64 Correct Answer Incorrect Answer

    Solution

    Given, тИЪb + (1/тИЪb) = 8
    On squaring both sides:
    (тИЪb + (1/тИЪb))2 = 82
    Expanding:
    b + 2 + (1/b) = 64
    Simplifying:
    b + (1/b) + 2 = 64
    Subtracting 2 from both sides:
    b + (1/b) = 62┬а
