    Which is the largest number among \[\sqrt{2},\] \[\sqrt[3]{3},\] \[\sqrt[6]{6}\]  and \[\sqrt[12]{12}?\]

    A) \[\sqrt{2}\]                                

    B) \[\sqrt[3]{3}\]

    C) \[\sqrt[6]{6}\]                            

    D) \[\sqrt[12]{12}\]

    Correct Answer: B

    Solution :

    \[\sqrt{2,}\] \[\sqrt[3]{3},\] \[\sqrt[6]{6}\] and \[\sqrt[12]{12}\] LCM of 2, 3, 6 and \[\sqrt[12]{12}\] Hence, given numbers can be changed as follows \[\sqrt[12]{{{2}^{6}}},\] \[\sqrt[12]{{{3}^{4}}},\]  \[\sqrt[12]{{{6}^{2}}}\] and \[\sqrt[12]{12}\] \[\sqrt[12]{64},\] \[\sqrt[12]{81},\] \[\sqrt[12]{36}\] and \[\sqrt[12]{12}\] Hence, \[\sqrt[3]{3}\] is the largest number.
