Use the properties of logarithms to expand ln⁡x2x+35\ln \sqrt [ 5 ] { \frac { x ^ { 2 } } { x + 3 } }ln5x+3x2 .

A) (ln⁡x) 2/5−ln⁡x⋅ln⁡3( \ln x ) ^ { 2 / 5 } - \ln x \cdot \ln 3(lnx) 2/5lnxln3
B) −5(2ln⁡x−ln⁡(x+3) ) - 5 ( 2 \ln x - \ln ( x + 3 ) ) 5(2lnxln(x+3) )
C) 15(2ln⁡x−ln⁡x⋅ln⁡3) \frac { 1 } { 5 } ( 2 \ln x - \ln x \cdot \ln 3 ) 51(2lnxlnxln3)
D) 25ln⁡x−15ln⁡(x+3) \frac { 2 } { 5 } \ln x - \frac { 1 } { 5 } \ln ( x + 3 ) 52lnx51ln(x+3)
E) ((ln⁡x) 2ln⁡x+ln⁡3) 1/5\left( \frac { ( \ln x ) ^ { 2 } } { \ln x + \ln 3 } \right) ^ { 1 / 5 }(lnx+ln3(lnx) 2) 1/5

Properties

Characteristics or rules that define how operations are performed on numbers and variables, including distributive, associative, and commutative properties.

Logarithms

Mathematical functions that determine the exponent or power to which a base number is raised to obtain a certain value, often written as \(\log_b(x)\).

Expand

To increase in size, number, or importance, or to make something increase in this way.

  • Engage logarithmic properties to achieve expansion and condensation of expressions.

Final Answer :
D
Explanation :
The expression can be expanded using the properties of logarithms: ln⁡x2x+35\ln \sqrt[5]{\frac{x^2}{x+3}}ln5x+3x2 simplifies to 15ln⁡(x2x+3)\frac{1}{5}\ln\left(\frac{x^2}{x+3}\right)51ln(x+3x2) , which further simplifies to 15(2ln⁡x−ln⁡(x+3))\frac{1}{5}(2\ln x - \ln(x+3))51(2lnxln(x+3)) , matching choice D.
