Need Logarithm Help.Hello I have been trying this questions forever to no avail. Could anyone help me? #2 20131124 22:45:41
Re: Need Logarithm Help.Hi;
Why do you need logarithms to solve a linear equation? Add .45 to both sides. For B, what are you allowed to use? A calculator? A log table? 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. #3 20131124 22:48:32
Re: Need Logarithm Help.Wow... Didn't know it was that simple... haha, but it is an assignment and unfortunately I need to use logarithm for it. I was thinking of putting "lg" on both sides, but not sure if that's the correct way. #4 20131124 22:52:43
Re: Need Logarithm Help.Do you have the right problem? 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. #5 20131124 22:59:43
Re: Need Logarithm Help.Apologies, knew something was not right. I typed wrongly. #6 20131124 23:03:11
Re: Need Logarithm Help.x^0.45 = 0.521 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. #8 20131124 23:14:15
Re: Need Logarithm Help.That is correct and what is log(x^(.45)) ? 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. #9 20131124 23:18:39
Re: Need Logarithm Help.I got 0.45 lgx = lg 0.521 #10 20131124 23:29:25
Re: Need Logarithm Help.What did you get for lg 0.521? 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. #11 20131124 23:32:37
Re: Need Logarithm Help.I got 0.283162276 and i divided that by 0.45 to get 0.629 #12 20131124 23:39:42
Re: Need Logarithm Help.That is correct. So what do you have left? 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. #13 20131124 23:41:16
Re: Need Logarithm Help.I have lg x = 0.629 left. #14 20131124 23:42:17
Re: Need Logarithm Help.What is the inverse of log(x)? 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. #16 20131124 23:45:47
Re: Need Logarithm Help.You are using the common log? 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. #18 20131124 23:52:47
Re: Need Logarithm Help.When we say log(3) we mean what power must 10 be raised to, to get 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.
