I think your answer is better.
Hi, I have two (basic) questions that I cant seem to understand. I'm in a self taught course where I learn everything from a book so it might have not explained everything fully. Question #1. solve s. My answer to the question is however I've been told the correct answer is . My question is, why are there two P's now instead of 1? Can anyone explain that to me? Thank you.
Interesting, this isnt the first time I've seen that however. One of the questions in my book: for a is similar, the answer given is . My answer: If this is another mistake could anyone provide an example where I could get an answer of two of the same variable from one incase I see it on a test? Thank you for the quick responses.
Wow, thank you Archie and everyone else. It makes complete sense now. You were right about the parenthesis which is why my answers were formatted a bit differently. I'll keep it in mind when solving questions like that again.
Edit: I can see there are 3 different answers for the 2nd question. I'm going to by the one Archie has since its in my solutions but is there generally more then one way to solve questions like that? Or was this just a simple mistake of not using parenthesis?
