logarithmic equations examples 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
Logarithmic equations Examples with answers The following logarithmic equation examples use the laws of logarithms and both methods detailed above Each example has its respective answer but it is recommended that you try to solve the exercises yourself before looking at Learn how to solve logarithmic equations in two 2 ways One way by setting the argument equal to each other and the other way by converting it as an exponential

We will be looking at two specific types of equations here In particular we will look at equations in which every term is a logarithm and we also look at equations in which all but one term in the equation is a logarithm and the term without the logarithm will be a constant Using the Definition of a Logarithm We have already seen that every logarithmic equation logb x y log b x y can be written as the exponential equation by x b y x We can use this fact to solve logarithmic equations where the argument is an algebraic expression For example consider the equation log2 6x 10 3 log 2 6 x 10 3
Where we read latex mathrm log b left x right latex as the logarithm with base b of x or the log base b of x the logarithm y is the exponent to which b must be raised to get x Also since the logarithmic and exponential functions switch the x and y values the domain and range of the exponential function are interchanged for the logarithmic function Sometimes we can use the product rule the quotient rule or the power rule of logarithms to help us with solving logarithmic equations This video shows how solve a logarithmic equation using properties of logarithms and some other algebra techniques

In this section we will take logarithmic equations and use properties of logarithms to restate them as exponential equations In the previous section we used the property of logarithms that said log b M p p log b M Solving Logarithmic Equations Equations involving logarithms and unknown variables can often be solved by employing the definition of the logarithm as well as several of its basic properties x log x a a xlogx a a Common mistakes to watch out for include frac log x a log x b neq log x big frac a b big logx
