      Question

      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
