Re: Simplify the following:27^n+2  6*3^3n+3/3^n9^n+2 #102 20130724 04:39:13
Re: Simplify the following:Okay, so far I have this,where is the mistake? 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. #103 20130724 04:52:16#104 20130724 04:56:41
Re: Simplify the following:How about doing some factoring there? 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. #105 20130724 05:03:21
Re: Simplify the following:It says we should simplify it. But I don't know if it could be factorized. I tried doing it but the six has given me a tough time, it cannot be reduced to have 3 in order to have the same base as the others. #106 20130724 05:08:07
Re: Simplify the following:How about simplifying 27^{3n+3} to start? 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:At the back of the book the answer given was 21. #110 20130724 05:31:13
Re: Simplify the following:That is incorrect. If post #102 is correct the answer I am getting is 7. Please look closely at post #102 and make sure I have the right problem as you see it in your text book. In mathematics, you don't understand things. You just get used to them.

Re: Simplify the following:Yes, they are the ones in the book, the book could be wrong so please let proceed. Last edited by EbenezerSon (20130724 05:59:38) #112 20130724 05:52:58#113 20130724 06:12:56
Re: Simplify the following:But I don't seem to understand those methods #114 20130724 06:22:20
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. #115 20130724 06:35:29
Re: Simplify the following:This problem is from indices. So I had thought all the bases would be equal so I can take them off and simplify the exponent. #116 20130724 06:40:22
Re: Simplify the following:You mean multiple 6 * 3^(3n+3) ? 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. #117 20130724 06:42:58
Re: Simplify the following:Yes to be > 18^(3n+3). But I see the eighteen cannot further be reduced to three, in order to have the same base with the others. #118 20130724 06:45:54
Re: Simplify the following:That is incorrect. You can not say 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. #119 20130724 06:48:29
Re: Simplify the following:Because so far all the problems I solved have the same bases, which is easy for me to take them off and simplify the exponent. #120 20130724 06:53:35
Re: Simplify the following:That is why I turned them all into the same bases, that way you can cancel and multiply when needed. 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. #121 20130724 06:56:10
Re: Simplify the following:Then I need to learn the laws of exponents, or do indices also teaches that? If not then please could you assist me learn it? #122 20130724 07:15:25
Re: Simplify the following:Yes, we can over the laws of exponents. Try here first. 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. #123 20130724 21:08:47
Re: Simplify the following:A^n = A*A*A*.....A* #124 20130724 21:24:34
Re: Simplify the following:A^n means A * A * A ... n times. 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:I have learnt that 5^0 = 1. Can you explain to me why it is equal to one?
