Stels [109]

Option C - Simplify the right side using the "difference of two logs is the log of the quotient" property.

Step-by-step explanation:

Given : Expression \ln (x-1)=\ln 6-\ln x

To find : What is the first step in solving  the expression ?

Solution :

Expression \ln (x-1)=\ln 6-\ln x

Step 1 - Simplify the right side using the "difference of two logs is the log of the quotient" property.

i.e. \ln a-\ln b=\ln(\frac{a}{b})

Apply the first step we get,

\ln (x-1)=\ln(\frac{6}{x})

Therefore, Option C is correct.
