14. Since 0 in ln(3x) - 0 is not a logarithm, the  property of logarithms cannot be used here.The difference shown cannot be written as a quotient of logarithms.The step ln(x2) = ln(3x) - (0) reduces to 

ln(x2) = ln(3x).The possible solutions are 0 and 3, with 0 being extraneous.

okay..i will pick 8!
