Re: Little question about exponentsdepends whether it says (2)^5 or (2^5) You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #4 20130703 03:02:24
Re: Little question about exponentsHi;
Without the brackets the minus sign stays. 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. #6 20130703 03:13:18

Re: Little question about exponentshi AlAllo As it happens you would get the same result if you did (2)^5 So here is a similar example where the denominator has an even power Whereas Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #8 20130703 03:32:39
Re: Little question about exponentsI don't think I made it clear what I wanted, the way you showed it to me bob, that I know. But I'm talking about the rules of exponenets. ex : #9 20130703 04:02:12
Re: Little question about exponentsDo you want to know how to use but when one of the xs is replaced by x So it will depend on whether n is odd or even. odd means result will be minus. even means result will be plus.

Re: Little question about exponentsYou can use codecogs to latex that expression correctly. In mathematics, you don't understand things. You just get used to them.

Re: Little question about exponentsThat is correct! 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
