    If √d + (1/√d) = 6, then find the value of d +

    (1/d).
    A 30 Correct Answer Incorrect Answer
    B 32 Correct Answer Incorrect Answer
    C 34 Correct Answer Incorrect Answer
    D 36 Correct Answer Incorrect Answer

    Solution

    Given, √d + (1/√d) = 6
    On squaring both sides:
    (√d + (1/√d)) 2 = 62
    Expanding:
    d + 2 + (1/d) = 36
    Simplifying:
    d + (1/d) + 2 = 36
    Subtracting 2 from both sides:
    d + (1/d) = 34
