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

    (1/t).
    A 21 Correct Answer Incorrect Answer
    B 22 Correct Answer Incorrect Answer
    C 23 Correct Answer Incorrect Answer
    D 25 Correct Answer Incorrect Answer

    Solution

    Given, √t + (1/√t) = 5
    On squaring both the sides,
    So, t + (1/t) + 2 × √t × (1/√t) = 25
    Or, t + (1/t) + 2 = 25
    So, t + (1/t) = 23
