Solving Logarithm Inequality Log x ((x+3)/(x-1)) > Log x x

AI Thread Summary
The discussion revolves around solving the logarithmic inequality Log x ((x+3)/(x-1)) > Log x x. Four conditions for the inequality are identified: -1 > x > 3, x > -3, x > 0, and x ≠ 1. There is confusion regarding how to express the solution correctly, with suggestions to avoid using "and" conditions and to state multiple conditions clearly. Participants emphasize that incompatible conditions should be reported as having no solutions. The conversation highlights the importance of clarity in mathematical expressions and proper forum etiquette for homework help.

Log x ((x+3)/(x-1) > Log x x ??

I've managed to find 4 conditions for this inequality:
1. -1 > x > 3
2. x > -3
3. x > 0
4. x ≠ 1

but I'm not sure how to write the solution. Is it " 0 < x & 1 < 0 < 3 " ?

Thanks.

I think you mistyped what this is supposed to be.

If you have multiple conditions, just write them out the way you would state them in English. For example, if I asked for the solutions to |x|>1 I would write "x>1 or x<-1". If someone asked for the solutions to |x2-4| > 1, I would write " x>sqrt(5) or -sqrt(3)<x<sqrt(3) or x<-sqrt(5)".

Notice you will never have an and condition. If you wrote something like " 1<x<5 and 2<x<7" you should just replace that with "2<x<5". If you have two conditions that are incompatible, just say there are no solutions rather than writing something like "1<x<3 and 5<x<6"

Hi. Thank you for the reply.

Could you help me to find x that would satisfy the inequality?
