Question 1207369
.


<pre>
The problem says that x is in the open interval (1,2).


It means that x > 1       (since on the number line, x is on the right of 1).


It also means that x < 2  (since on the number line, x is on the left of 2).


These are the answers to your questions (1) and (2).

Answered and explained, in full.


Your problem is that you do not understand elementary standard mathematical writing, 
in no one of its words, terms and/or conceptions, as well as in no one single mathematical symbol.


It means that you do not have necessary pre-requisite knowledge to read, understand and solve these problems.



To learn Math this way without following right logic is a deliberately losing strategy, which will not lead to success.


To learn mathematics successfully, you need to follow carefully designed courses where all concepts are introduced sequentially.


Good school courses have been developed over centuries, so the best thing you can do is to follow those well-designed courses.
