    If √f + (1/√f) = 5, then find the value of f +

    (1/f).
    A 20 Correct Answer Incorrect Answer
    B 22 Correct Answer Incorrect Answer
    C 23 Correct Answer Incorrect Answer
    D 25 Correct Answer Incorrect Answer

    Solution

    Given, √f + (1/√f) = 5
    On squaring both sides:
    (√f + (1/√f)) 2 = 52
    Expanding:
    f + 2 + (1/f) = 25
    Simplifying:
    f + (1/f) + 2 = 25
    Subtracting 2 from both sides:
    f + (1/f) = 23
