`log[(root3(x^(2))xxy)/(root5(z^(2)))]`=_______A. `logx^(2//3) - log z^(2//5) + log y`B. `log x^(3//2)-logy - log z^(5//2)`C. `log x^(2//3)-log y + log z^(2//5)`D. None of these |

Answer» Correct Answer - A (i) Use the identities log mn= log m + log n , `log m/n ` = log m - log n and `log x^(n) = n log x`. `((root3(x^(2)).y)/(root5(z^(2))))log(((x^(2//3).y)/(z^(2//5))))` (iii) Use `log (a/b) = log a - log b and log ab = log a + 10 log b ` simplify. |
