Solving Problems Involving Logarithmic Functions . A logarithmic equation is an equation that involves at least one logarithmic function. In general, there are two cases for logarithmic equations. Case 1) In this case, we have logarithmic functions with similar bases on both sides of an equation. If the bases are the same, then the arguments ...
as a decaying exponential function would, we will look for a logarithmic model of the form y = a + b ln x where b < 0 for the data. To have the calculator find a regression equation of the form y = a + b ln x, use LnReg from the STAT CALC screen. The equation of a logarithmic function that models the data is y = 34.1786 - 5.6826 ln x.

Using the Definition of a Logarithm to Solve Logarithmic Equations Exponential Equations Practice II ... Solving Applied Problems Using Exponential and Logarithmic Equations ... Now it's your turn to practice graphing logarithmic functions. If you need help, there are hints and videos.
In this section we will now take a look at solving logarithmic equations, or equations with logarithms in them. We will be looking at two specific types of equations here. ... In other words, if we’ve got two logs in the problem, one on either side of an equal sign and both with a coefficient of one, then we can just drop the logarithms.
Solving log and natural logarithmic equations in many ways. All types of log examples covered. Solving videos at the bottom of the page. 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. Step 4: Check your answers.
Example 1.3 Solve exe2 = e4 ex+1. Solution: Using the product and quotient properties of exponents we can rewrite the equation as ex+2 = e4 (x+1) = e4 x 1 = e3 x Since the exponential function ex is one-to-one, we know the exponents are equal: x+ 2 = 3 x Solving for x gives x = 1 2. 2 Log Problems Example 2.1 Wite the follwing equations in ...
