Use the properties of logarithms to expand ln⁡x2(y−5) \ln x ^ { 2 } ( y - 5 ) lnx2(y5) .

A) 2ln⁡x+ln⁡(y−5) 2 \ln x + \ln ( y - 5 ) 2lnx+ln(y5)
B) 2ln⁡x+ln⁡yln⁡52 \ln x + \frac { \ln y } { \ln 5 }2lnx+ln5lny
C) (ln⁡x) 2+ln⁡yln⁡5( \ln x ) ^ { 2 } + \frac { \ln y } { \ln 5 }(lnx) 2+ln5lny
D) (ln⁡x) 2(ln⁡y−ln⁡5) ( \ln x ) ^ { 2 } ( \ln y - \ln 5 ) (lnx) 2(lnyln5)
E) 2(ln⁡x+ln⁡(y−5) ) 2 ( \ln x + \ln ( y - 5 ) ) 2(lnx+ln(y5) )

Final Answer :
A
Explanation :
By the properties of logarithms, we have ln⁡x2(y−5)=ln⁡(x2)+ln⁡(y−5)=2ln⁡x+ln⁡(y−5).\ln x^2(y-5)=\ln(x^2)+\ln(y-5)=2\ln x + \ln(y-5).lnx2(y5)=ln(x2)+ln(y5)=2lnx+ln(y5).
Therefore, the correct answer is A.
