Homework Statement
from -lnIxI to lnI x^-1I , I try to go from -lnIxI to lnI x^-1I by using some properties.
Homework Equations
- lnIxI
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.
