Question:৪সরল  `(root(3)(7^2) . root(3)(7))/sqrt(7)`

Answer সমাধান:  `(root(3)(7^2) . root(3)(7))/sqrt(7)`
            `= ((7^2)^(1/3) . 7^(1/3))/7^(1/2)`

            `= 7^(2/3 + 1/3 - 1/2)`

            `= 7^((4 + 2 - 3)/6)`

            `= 7^(3/6)`

            `= 7^(1/2)`

            `= sqrt (7)`    Ans.
