    Express \[\underline{a\times a\times a}\] \[\times \] \[\underline{c\times c\times c\times c}\] \[\times \] \[b\] \[\times \] \[b\] in exponential form.

    A)  \[{{a}^{3}}{{c}^{3}}{{b}^{3}}\]                          

    B)  \[{{a}^{3}}{{c}^{3}}b\]

    C)  \[{{a}^{3}}{{c}^{3}}{{b}^{2}}\]                   

    D)  \[{{a}^{3}}{{c}^{4}}{{b}^{2}}\]

    Correct Answer: D

    Solution :

    a three times \[\Rightarrow {{a}^{2}};\] c four times \[\Rightarrow {{c}^{4}};\] b two times \[\Rightarrow {{b}^{2}}\,\,\,\therefore \,\,\,\,\,{{a}^{3}}{{c}^{4}}{{b}^{2}}\]
