Re: Simplify the following:Something is wrong there. Are you sure you copied the problem correctly? The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #227 20130805 15:46:19
Re: Simplify the following:log(y^2/2x) = log2ylog2x In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #228 20130805 23:02:51
Re: Simplify the following:it's log2(yx) #229 20130805 23:05:55
Re: Simplify the following:Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #230 20130805 23:36:17
Re: Simplify the following:Errr, I dont normally put bracket around figures as you normally do. #231 20130805 23:39:18
Re: Simplify the following:
Math has to be precise. More precise than anything else you do. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Simplify the following:Thanks, Bobbym. #233 20130806 00:09:24

Re: Simplify the following:But Bobbym I havent envisioned that bracket of the right hand side could cause any thing, but I think; #235 20130806 00:34:07
Re: Simplify the following:Okay, we have the original problem looking like this In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #236 20130806 00:45:03
Re: Simplify the following:Oops. Bobym. #237 20130806 00:52:07
Re: Simplify the following:So you want this? It looks a lot like the earlier one. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #238 20130806 01:45:39

Re: Simplify the following:That book is awful. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #240 20130806 01:57:53
Re: Simplify the following:But is the answer I had the same as yours when you solved? #241 20130806 01:59:39
Re: Simplify the following:Those are all correct answers with methods shown. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #242 20130806 02:11:35
Re: Simplify the following:Is your interpretation the ones the book should have used? #243 20130806 02:18:05
Re: Simplify the following:Let's see what happens. 10^ to both sides Multiply both sides by 2x In mathematics, you don't understand things. You just get used to them.

With a careful look at signs I think should be, #245 20130808 02:02:18#246 20130808 21:50:27

Re: Simplify the following:Please could you demostrate to me?, c'os I can't adentify it. #249 20130808 22:55:49
Re: Simplify the following:How did 3(x+1) become 3x3? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #250 20130808 23:23:00
Re: Simplify the following:I see, then let me check the original one and come back.
