D) ln⁡(12−3x−y) \ln ( 12 - 3 x - y ) ln(123xy)
E) ln⁡81x3y\ln \frac { 81 } { x ^ { 3 } y }lnx3y81

Logarithms

The exponent or power to which a base must be raised to produce a given number, typically used in solving exponential equations.

Condense

In mathematics, to simplify an expression or equation by combining like terms or using algebraic methods to make it more compact.

Final Answer :
E
Explanation :
Using the properties of logarithms, 4ln⁡3−3ln⁡x−ln⁡y4 \ln 3 - 3 \ln x - \ln y4ln33lnxlny can be condensed as follows: - 4ln⁡34 \ln 34ln3 becomes ln⁡34\ln 3^4ln34 or ln⁡81\ln 81ln81 ,- −3ln⁡x-3 \ln x3lnx becomes −ln⁡x3-\ln x^3lnx3 or ln⁡1x3\ln \frac{1}{x^3}lnx31 ,- −ln⁡y- \ln ylny becomes ln⁡1y\ln \frac{1}{y}lny1 .Combining these using the property that ln⁡a+ln⁡b=ln⁡(ab)\ln a + \ln b = \ln (ab)lna+lnb=ln(ab) and ln⁡a−ln⁡b=ln⁡(ab)\ln a - \ln b = \ln \left(\frac{a}{b}\right)lnalnb=ln(ba) , we get ln⁡81x3y\ln \frac{81}{x^3 y}lnx3y81 .
