Answer» Correct Answer - Option 2 : 2 CONCEPT:
CALCULATION: Given is log(6x) − log(6−x) = log(3). By Quotient property of logarithms we can write it as - \( ⇒ \log \left( {\frac{{6x}}{{6 - x}}} \right) = \log 3\) On dropping log from both the sides we get \(\left( {\frac{{6x}}{{6 - x}}} \right) = 3\). ⇒ 6x = 3(6 - x) ⇒ 9x = 18 ⇒ x = 2 Therefore, option (3) is the correct answer. |
