 Oct5 awarded Notable Question Sep5 awarded Popular Question Jul2 awarded Curious Jun3 comment Factoring in the derivative of a rational function Thank you for your references Jun3 comment Factoring in the derivative of a rational function Thank you very much for your examples in continuing it. Jun3 accepted Factoring in the derivative of a rational function Jun3 comment Factoring in the derivative of a rational function Ahhhh. So much time looking at it and I didn't realise this. I don't know about the factor theorem, something to look at. Thank you for your answer. Jun3 awarded Yearling Jun3 asked Factoring in the derivative of a rational function Jun3 awarded Commentator Jun3 comment Finding Domain of a Function with a Fraction Inside a Square Root Thank you for your answer ! I didn't think about approaching it at once like here, but I don't get the part of finding the domain so quickly, maybe a trick? Sorry I'm unable to see the "middle path" of it! Jun3 comment Finding Domain of a Function with a Fraction Inside a Square Root Thank you very much. I didn't remember about this procedure but now makes all sense. Much appreciated Jun3 accepted Finding Domain of a Function with a Fraction Inside a Square Root Jun3 asked Finding Domain of a Function with a Fraction Inside a Square Root Oct13 comment Comparing Powers of Different Bases Thanks once again for the explanation @ArturoMagidin Oct13 accepted Comparing Powers of Different Bases Oct12 comment Comparing Powers of Different Bases @ArturoMagidin I know :-) But which one is bigger: $2^{2000}$ or $10^{800}$? I'd like to know about cases like this one. Edit: You should post this edit in your comment as answer. Oct12 asked Comparing Powers of Different Bases Oct12 accepted Homework with logarithms May12 comment Homework with logarithms Very clever! Well, following the idea $\log_{c}2 = 1$ (if I'm not mistaken), but unfortunately I've just checked the workbook answers (answers are provided, resolutions not) and it should be 4, not 11. Hmm, probably there is something wrong with the exercise. I'll search for my teacher tomorrow in school and ask him about this exercise. Thanks a lot you all, I'll post any news. cc @Isaac @GEdgar @Nana
