    Question

    Simplify: 40966+506254+219523+3364\text{Simplify: } \sqrt[6]{4096} + \sqrt[4]{50625} + \sqrt[3]{21952} + \sqrt{3364}

    A.

    55

    B.

    105

    C.

    24

    D.

    75

    Correct option is B

    Given:
    We need to simplify the expression:
    40966+506254+219523+3364\sqrt[6]{4096} + \sqrt[4]{50625} + \sqrt[3]{21952} + \sqrt{3364}​​
    Solution:
    4096=21240966=2126=212/6=22=450625=154506254=1544=154/4=1521952=26×73219523=26×733=26/3×73/3=22×7=4×7=283364=22×2923364=22×292=2×29=584096 = 2^{12}\\\sqrt[6]{4096} = \sqrt[6]{2^{12}} = 2^{12/6} = 2^2 = 4\\50625 = 15^4\\\sqrt[4]{50625} = \sqrt[4]{15^4} = 15^{4/4} = 15\\21952 = 2^6 \times 7^3\\\sqrt[3]{21952} = \sqrt[3]{2^6 \times 7^3} = 2^{6/3} \times 7^{3/3} = 2^2 \times 7 = 4 \times 7 = 28\\3364 = 2^2 \times 29^2\\\sqrt{3364} = \sqrt{2^2 \times 29^2} = 2 \times 29 = 58\\​​
    40966+506254+219523+3364\sqrt[6]{4096} + \sqrt[4]{50625} + \sqrt[3]{21952} + \sqrt{3364} ​​
    = 4 + 15 + 28 + 58 
    = 105
