Homework Help Overview

The discussion revolves around solving a logarithmic inequality involving the expression Log x ((x+3)/(x-1)) > Log x x. Participants are attempting to determine the conditions under which this inequality holds true.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to identify conditions for the inequality, listing four specific constraints. Some participants question the correctness of the stated conditions and suggest clarifying how to express multiple conditions in a coherent manner.

Discussion Status

The discussion is ongoing, with participants exploring the formulation of the inequality and the conditions that need to be satisfied. Guidance has been offered regarding how to articulate the conditions clearly, but there is no consensus on the correct interpretation or solution yet.

Contextual Notes

There are indications of confusion regarding the notation and expression of conditions, as well as a reminder about posting in the appropriate forum for homework-related questions.

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?
