16 Νοε 2022 · Solve each of the following equations. Here is a set of practice problems to accompany the Solving Logarithm Equations section of the Exponential and Logarithm Functions chapter of the notes for Paul Dawkins Algebra course at Lamar University.
Let’s learn how to solve logarithmic equations by going over some examples. Since we want to transform the left side into a single logarithmic equation, we should use the Product Rule in reverse to condense it. Here is the rule, just in case you forgot. Drop the logs, set the arguments (stuff inside the parenthesis) equal to each other.
Solve for x : log 2 (x + 3) + log 2 (x - 3) = 4. Solution : log 2 (x + 3) + log 2 (x - 3) = 4. Use the fundamental law of logarithm. log 2 [(x + 3)(x - 3)] = 4. Convert to exponential form. (x + 3)(x - 3) = 2 4. x 2 - 3 2 = 16. x 2 - 9 = 16. x 2 = 25. √x 2 = √25. x = ± 5. x = -5 or 5. But, x = -5 will not work with the given equation.
To solve this type of equations, here are the steps: Simplify the logarithmic equations by applying the appropriate laws of logarithms. Rewrite the logarithmic equation in exponential form. Now simplify the exponent and solve for the variable. Verify your answer by substituting it back in the logarithmic equation.
Step 1: Use the properties of the logarithm to isolate the log on one side. Step 2: Apply the definition of the logarithm and rewrite it as an exponential equation. Step 3: Solve the resulting equation.
Here, we will review the process used to solve logarithmic equation exercises. We will look at a summary of the two methods that we can apply to obtain the answer. In addition, we will look at several examples with answers to fully master the topic of logarithmic equations.
16 Νοε 2022 · In this section we will discuss a couple of methods for solving equations that contain logarithms. Also, as we’ll see, with one of the methods we will need to be careful of the results of the method as it is always possible that the method gives values that are, in fact, not solutions to the equation.
