Solving Exponential Equations Algebraically Isolate the exponential expression on one side. Take the logarithm of both sides.

Change of base formula. Summary Students continue an examination of logarithms in the Research and Revise stage by studying two types of logarithms—common logarithms and natural logarithm. In this study, they take notes about the two special types of logarithms, why they are useful, and how to convert to these forms by using the change of base formula.

Then students see how these types of logarithms can be applied to solve exponential equations. They compute a set of practice problems and apply the skills learned in class. Engineering Connection All types of engineers use natural and common logarithms.

Chemical engineers use them to measure radioactive decay, and pH solutions, which are measured on a logarithmic scale. Exponential equations and logarithms are used to measure earthquakes and to predict how fast your bank account might grow.

Biomedical engineers use them to measure cell decay and growth, and also to measure light intensity for bone mineral density measurements, the focus of this unit. Learning Objectives After this lesson, students should be able to: Define the number e. Define the common and natural logarithms.

Use common and natural logarithms to evaluate expressions. Use the change of base formula to convert to a common or natural logarithm in order to evaluate expressions and solve equations. More Curriculum Like This Statistical Analysis of Flexible Circuits Students are introduced to the technology of flexible circuits, some applications and the photolithography fabrication process.

They are challenged to determine if the fabrication process results in a change in the circuit dimensions since, as circuits get smaller and smaller nano-circuitsthis c High School Lesson Bone Density Math and Logarithm Introduction Students examine the definition, history and relationship to exponents; they rewrite exponents as logarithms and vice versa, evaluating expressions, solving for a missing piece.

High School Lesson A Tale of Friction High school students learn how engineers mathematically design roller coaster paths using the approach that a curved path can be approximated by a sequence of many short inclines. They apply basic calculus and the work-energy theorem for non-conservative forces to quantify the friction along a curve High School Lesson Bone Mineral Density Math and Beer's Law Students revisit the mathematics required to find bone mineral density, to which they were introduced in lesson 2 of this unit.

They learn the equation to find intensity, Beer's law, and how to use it. Then they complete a sheet of practice problems that use the equation. In the ASN, standards are hierarchically structured: Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.

Grades 9 - 12 Details View more aligned curriculum Do you agree with this alignment? Yes No Thanks for your feedback!Logarithmic equations contain logarithmic expressions and constants.

A logarithm is another way to write an exponent and is defined by if and only if. When one side of the equation contains a single logarithm and the other side contains a constant, the equation can be solved by rewriting the equation as an equivalent exponential equation using the definition of logarithm from above.

Math Exponential and Logarithmic Functions PRACTICE EXAM All of the following are exponential functions except: A. C. y = 2x D. y = 3x B. y = 1x 2. . Solving Logarithmic Equations Algebraically. Use properties of logarithms to combine the sum, difference, and/or constant multiples of logarithms into a single logarithm.

Apply an exponential function to both sides. The base used in the exponential function should be the same as the base in the logarithmic function.

Rewriting Logarithmic Expressions The properties of logarithms are useful for rewriting logarithmic expressions in forms that simplify the operations of algebra. This is true because these proper-ties convert complicated products, quotients, and exponential forms into simpler sums, differences, and products, respectively.
