This is just a quadratic equation and everyone in this class should be able to solve that. The last step to this problem is to check the two solutions to the quadratic equation in the original equation.

Often there will be more than one logarithm in the equation. When this happens we will need to use one or more of the following properties to combine all the logarithms into a single logarithm. Not a major issue, but those minus signs on coefficients are really easy to lose on occasion.

Show Solution As with the last example, first combine the logarithms into a single logarithm. Show Solution The first step is to get the exponential all by itself on one side of the equation with a coefficient of one. Show Solution Now, in this case it looks like the best logarithm to use is the common logarithm since left hand side has a base of This is an equation similar to the first two that we did in this section.

The next equation is a more complicated looking at least… example similar to the previous one. Show Solution First get the two logarithms combined into a single logarithm.

We will get these kinds of solutions on occasion. It is also important to make sure that you do the checks in the original equation.

The only difference between this quadratic equation and those you are probably used to seeing is that there are numbers in it that are not integers, or at worst, fractions. Note however, that if you can divide a term out then you can also factor it out if the equation is written properly.

However, we do need to be careful. On the other hand, the second solution, 3. Due to the nature of the mathematics on this site it is best views in landscape mode. First, we take the logarithm of both sides and then use the property to simplify the equation.

Doing that we can see that the first solution, If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.

Also, be careful in solving equations containing logarithms to not get locked into the idea that you will get two potential solutions and only one of these will work. There is one more problem that we should work.

Once this has been done we can proceed as we did in the previous example.

It is possible to have problems where both are solutions and where neither are solutions.Problem 1: Write the logarithmic equation 8 log73x = in exponential form. Problem 2: Write the logarithmic equation x log = in exponential form. Problem 3: Wr ite the logarithmic equation 4 xlog=91 in exponential form.

Problem 4: Write the logarithmic equation 3 logx73 = in exponential form. Before you try to understand the formula for how to rewrite a logarithm equation as exponential equation, you should be comfortable solving exponential equations.

As the examples below will show you, a logarithmic expression like $$ log_2 $$ is simply a different way of writing an exponent!

For x =-3 we get a Log[2,0] in the first term of the left-hand side of the equation that Mathematica cancels with another Log[0]; same for the second term and x = -2/3.

The situation for x=-2 is different. Stack Exchange network consists of Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share.

1 Rewriting Exponential and Logarithmic equations When solving an exponential or logarithmic equation, the rst step is to rewrite the equation so that the unknown is isolated on one side. To do this we use all the mad skillz we have been developing in rewriting equations.
