Use the properties of logarithms to expand ln⁡xy2z2\ln \frac { x y ^ { 2 } } { z ^ { 2 } }lnz2xy2 .

A) ln⁡x−2ln⁡y−2ln⁡z\ln x - 2 \ln y - 2 \ln zlnx2lny2lnz
B) ln⁡(x+2y−2z) \ln ( x + 2 y - 2 z ) ln(x+2y2z)
C) ln⁡x⋅(ln⁡y) 2(ln⁡z) 2\frac { \ln x \cdot ( \ln y ) ^ { 2 } } { ( \ln z ) ^ { 2 } }(lnz) 2lnx(lny) 2
D) ln⁡x+(ln⁡y) 2−(ln⁡z) 2\ln x + ( \ln y ) ^ { 2 } - ( \ln z ) ^ { 2 }lnx+(lny) 2(lnz) 2
E) ln⁡x+2ln⁡y−2ln⁡z\ln x + 2 \ln y - 2 \ln zlnx+2lny2lnz

Final Answer :
E
Explanation :
Using the properties of logarithms, the expression ln⁡xy2z2\ln \frac { x y ^ { 2 } } { z ^ { 2 } }lnz2xy2 can be expanded as ln⁡x+ln⁡y2−ln⁡z2\ln x + \ln y^2 - \ln z^2lnx+lny2lnz2 . Applying the power rule of logarithms ( ln⁡ab=bln⁡a\ln a^b = b \ln alnab=blna ), this simplifies to ln⁡x+2ln⁡y−2ln⁡z\ln x + 2 \ln y - 2 \ln zlnx+2lny2lnz .
