    If cube root of 175616 is 56, then the value of \[\sqrt[3]{175.616}+\sqrt[3]{0.175616}+\sqrt[3]{0.000175616}\] is equal to

    A)  0.168              

    B)  62.16

    C)  6.216  

    D)  6.116

    Correct Answer: C

    Solution :

    \[\because \] \[\sqrt[3]{175616}=56\] Now, \[\sqrt[3]{175.616}+\sqrt[3]{0.175616}+\sqrt[3]{0.000175616}\] \[\sqrt[3]{\frac{175616}{1000}}+\sqrt[3]{\frac{175616}{1000000}}+\sqrt[3]{\frac{175616}{1000000000}}+\]             \[=\frac{56}{10}+\frac{56}{100}+\frac{56}{1000}\]             \[=5.6+0.56+0.056\]             \[=6.216\]
