Can students easily determine what this evaluates to, that is, log 381 = 4? Practice a bit more and address potential gaps.įor more advanced practice examples on evaluating logarithms, use this brief online activity by Khan Academy. What about evaluating logarithms? Have students acquired proficiency in evaluating a given log? For instance, write log 381 = x on the whiteboard. Can most students easily say that the equivalent exponent is 2 x = 16? For example, write a simple log on the whiteboard, such as log 216 = x, and ask students to transform it into an exponent. Then, check if there are any gaps in what students have learned so far on logarithms. The video introduces what logarithms represent, by using examples. You can also play this video in your class. So logarithms are the opposite of exponentials, as they basically “undo” exponentials. You can present this in the following manner: That is, log a x (“log base a of x”) is the exponent to which a must be raised to get x. Remind students that a logarithm is an exponent. Start your lesson on the properties of logarithms by briefly reviewing what logarithms are. Strategies for Teaching Properties of Logarithms Review Logarithms
We share a few such strategies in this article. This is because students can simplify and evaluate logarithms with the help of these properties.Įven though log lessons may be challenging, math teachers can help make them more engaging and accessible by using various teaching strategies. When pre-calculus students learn about logarithmic functions, one of the most important lessons they come across is the properties of logarithms. So what is there to lose anyway? Cheers and all the best. I have used it through many algebra classes – Pre Algebra, Algebra 2 and Intermediate algebra. By simply typing in a problem homework a step by step solution would appear by a click on Solve. A truly great piece of algebra program is Algebrator software. I remember having often faced difficulties with factoring, binomial formula and perfect square trinomial. Please let me know where I can find this piece of program. I do admit that dozing off is not a solution to it either. I am not trying to run away from my problems. My grades have really improved within the last year.
I was at ease with it within few minutes. A colleague of mine told me to give one last chance and sent me a copy of Algebrator. I had even considered the option of leaving math and selecting some other course. Hello, just a year ago, I was stuck in a similar scenario. What is attractive about it is that it hand holds you to the solutions rather than simply giving the answer. I would select Algebrator for the kind of elucidation that you are in the look out for. It came across to me as superb as any tutor can be. There are some good algebra programs that you can check out. If you are not able to get a good tutor or some one to sit and sort out your problem or if if it is too expensive, then there might be another way out. How about some more particulars about your problem with simplifying logarithms calculator? I might be able to help you with. I have my midterms coming up in a a couple of days from now and I don’t know what to do ? Is there anyone out there who can actually take out some time and help me with my problems ? Any sort of help would be highly appreciated. I’m fed up of trying to solve problems on simplifying logarithms calculator and some related topics such as triangle similarity and quadratic equations. Well there are just two people who can guide me at this point in time, either it has to be some math guru or it has to be God himself.
