Properties of logarithms Video transcript We're asked to simplify log base 5 of 25 to the x power over y. So we can use some logarithm properties. And I do agree that this does require some simplification over here, that having this right over here inside of the logarithm is not a pleasant thing to look at.
Students evaluate each logarithmic expression in order to determine who wins the round. The final two problems on the homework could not be solved exactly without logarithms, although many students will have estimated the solutions well.
I write these problems on the board and ask students to share how they approached them. I tell them that the way to solve it exactly is to use logarithms [MP6]. We go through a few examples on the board of using logarithms to provide some exact solutions of exponential equations. Although many textbooks teach students to solve in terms of base 10 or base e, modern calculators can provide approximations for logarithms of any base.
Because logarithms are a minor topic in the Common Core State Standards, I do not spend much time developing the concept.
My goals for Algebra 2 coverage of logarithms are to make sure that students can understand that logarithms are exponents and that "taking the log base b" is the inverse of "raising b to the power" translate between exponential notation and logarithmic notation F.
This is a collection of equations to solve that require the use of logarithms. I instruct my students to provide "exact answers" and then approximate to a decimal.
I want my students to understand that in math class we provide exact answers so that the answer can be rounded with the appropriate level of precision when solving an applied problem [MP6].
