    If cube root of 175616 is 56, then the value of \[\sqrt[3]{176.616}+\sqrt[3]{0.175616}+\sqrt[3]{0.000175616}\] is equal to

    A) 0.168               

    B) 62.16

    C) 6.216   

    D) 6.116

    Correct Answer: C

    Solution :

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