Use the properties of logarithms to expand lnxy2z2\ln \frac { x y ^ { 2 } } { z ^ { 2 } }lnz2xy2 .
A) lnx−2lny−2lnz\ln x - 2 \ln y - 2 \ln zlnx−2lny−2lnz
B) ln(x+2y−2z) \ln ( x + 2 y - 2 z ) ln(x+2y−2z)
C) lnx⋅(lny) 2(lnz) 2\frac { \ln x \cdot ( \ln y ) ^ { 2 } } { ( \ln z ) ^ { 2 } }(lnz) 2lnx⋅(lny) 2
D) lnx+(lny) 2−(lnz) 2\ln x + ( \ln y ) ^ { 2 } - ( \ln z ) ^ { 2 }lnx+(lny) 2−(lnz) 2
E) lnx+2lny−2lnz\ln x + 2 \ln y - 2 \ln zlnx+2lny−2lnz

Final Answer :
E
Explanation :
Using the properties of logarithms, the expression lnxy2z2\ln \frac { x y ^ { 2 } } { z ^ { 2 } }lnz2xy2 can be expanded as lnx+lny2−lnz2\ln x + \ln y^2 - \ln z^2lnx+lny2−lnz2 . Applying the power rule of logarithms ( lnab=blna\ln a^b = b \ln alnab=blna ), this simplifies to lnx+2lny−2lnz\ln x + 2 \ln y - 2 \ln zlnx+2lny−2lnz .
