Question

( log _{e}(x+2)+log _{e}(x-2 y+2)=2 log _{e}(x-2) )
( log _{7}+log _{B}=log (A B) )
( log _{e}((x+2)(x-2 y+2)]=log _{e}(x-2)^{2} )
( (x+7)(x+2-2 y)=(x-2)^{2} )
( (x+2)(x+2)-2 y(x+z)=(x-2)^{2} )
( x^{2} y^{2}-2 y^{2} )

# 13. If loge (x+2)+loge (x-2y+z) = 2 loge (x-z), then (a) xy + yz = 2xz (b) y + yz = xz (c) x+yz=2yz (d) none of these Cx+y
