    If √m + (1/√m) = 7, then find the value of m +

    (1/m).
    A 45 Correct Answer Incorrect Answer
    B 46 Correct Answer Incorrect Answer
    C 47 Correct Answer Incorrect Answer
    D 49 Correct Answer Incorrect Answer

    Solution

    Given, √m + (1/√m) = 7
    On squaring both the sides,
    So, m + (1/m) + 2 × √m × (1/√m) = 49
    Or, m + (1/m) + 2 = 49
    So, m + (1/m) = 47
