1. The problem statement, all variables and given/known data from -lnIxI to lnI x^-1I , I try to go from -lnIxI to lnI x^-1I by using some properties. 2. Relevant equations - lnIxI 3. The attempt at a solution First I write the -lnIxI as -1*lnIxI and then I use -1 as an exponent to absolute value of x in the natural log that is ln ( IxI^-1) and then I take -1 inside the paranthesis and I arrive to ln Ix^-1I which is also ln I 1/x I. Are my steps correct? If not, which step is incorrect? Thank you.
