Symbolic substitution

Hi

Simple helps on symbolic substitutions. How do you substitute so the final answer is the same as the 2nd Z(s)?

Thanks for all the helps

Isn't it the very same question as was discussed here

Hi

Sorry yes exactly the same. I selected Knowledge Based and I though it did not go anywhere so I generated another one which I labeled as Electrical Engineering. 

Thanks

Labels for posts are rather useless and I don't think that there are many people who care about.

But as far as I am aware "Knowledge Base" is not a label category. Thanks to my Adblocker I don't see those labels or announcements, search area, kudos, etc. When I open the site from my bookmark, I just want to see the threads without any need for scrolling down 😉
Despite any label all threads are collected in the very same space/forum. I guess that you could filter for those labels if for some reason you are interested in not seeing all threads.
