How do you solve #log_3 x-log_3(x-1)=1#? Precalculus Properties of Logarithmic Functions Common Logs 1 Answer Cesareo R. Aug 17, 2016 Answer: #x = 3/2# Explanation: #log_3 x-log_3(x-1)=1 = log_3 3# so #log_3(x/(x-1))=log_3 3# so #x/(x-1) = 3# or #x =3(x-1)# Solving for #x# gives #x = 3/2#. Verifying the feasibility #log_3 (3/2) - log_3(1/2)=log_3 3# So, #x = 3/2# is the solution. Related questions What is the common logarithm of 10? How do I find the common logarithm of a number?
