  • Exponential And Logarithmic Functions

    Properties 3 and 4 leads to a nice relationship between the logarithm and exponential function. This is a nice fact to remember on occasion. We will be looking at this property in detail in a couple of sections. We will just need to be careful with these properties and make sure to use them correctly. Also, note that there are no rules on how to break up the logarithm of the sum or difference of two terms. Note that all of the properties given to this point are valid for both the common and natural logarithms. Example 4 Simplify each of the following logarithms. When we say simplify we really mean to say that we want to use as many of the logarithm properties as we can. In order to use Property 7 the whole term in the logarithm needs to be raised to the power. We do, however, have a product inside the logarithm so we can use Property 5 on this logarithm. In these cases it is almost always best to deal with the quotient before dealing with the product. Here is the first step in this part.

  • Chapter 7 - Exponential And Logarithmic Functions - Chapter Test - Page 491: 1

    Therefore, we need to have a set of parenthesis there to make sure that this is taken care of correctly. The second logarithm is as simplified as we can make it. Also, we can only deal with exponents if the term as a whole is raised to the exponent. It needs to be the whole term squared, as in the first logarithm. Here is the final answer for this problem. This next set of examples is probably more important than the previous set. We will be doing this kind of logarithm work in a couple of sections. Example 5 Write each of the following as a single logarithm with a coefficient of 1. We will have expressions that look like the right side of the property and use the property to write it so it looks like the left side of the property. This will use Property 7 in reverse. In this direction, Property 7 says that we can move the coefficient of a logarithm up to become a power on the term inside the logarithm. Here is that step for this part. This means that we can use Property 5 in reverse.

    Here is the answer for this part. When using Property 6 in reverse remember that the term from the logarithm that is subtracted off goes in the denominator of the quotient. Here is the answer to this part.

  • 7.4: Properties Of The Logarithm

    Use logarithms to solve exponential equations. Use the definition of a logarithm to solve logarithmic equations. Use the one-to-one property of logarithms to solve logarithmic equations. Solve applied problems involving exponential and logarithmic equations. Wild rabbits in Australia. Because Australia had few predators and ample food, the rabbit population exploded. In fewer than ten years, the rabbit population numbered in the millions. Uncontrolled population growth, as in the wild rabbits in Australia, can be modeled with exponential functions. Equations resulting from those exponential functions can be solved to analyze and make predictions about exponential growth. In this section, we will learn techniques for solving exponential functions.

  • Unit: Exponential & Logarithmic Functions

    Recall that the one-to-one property of exponential functions tells us that, for any real numbers and where if and only if In other words, when an exponential equation has the same base on each side, the exponents must be equal. This also applies when the exponents are algebraic expressions. Therefore, we can solve many exponential equations by using the rules of exponents to rewrite each side as a power with the same base. Then, we use the fact that exponential functions are one-to-one to set the exponents equal to one another, and solve for the unknown. For example, consider the equation To solve for we use the division property of exponents to rewrite the right side so that both sides have the common base, Then we apply the one-to-one property of exponents by setting the exponents equal to one another and solving for Using the One-to-One Property of Exponential Functions to Solve Exponential Equations For any algebraic expressions and any positive real number Given an exponential equation with the form where and are algebraic expressions with an unknown, solve for the unknown.

  • Exponential And Logarithmic Functions

    Use the rules of exponents to simplify, if necessary, so that the resulting equation has the form Use the one-to-one property to set the exponents equal. In these cases, we simply rewrite the terms in the equation as powers with a common base, and solve using the one-to-one property. For example, consider the equation We can rewrite both sides of this equation as a power of Then we apply the rules of exponents, along with the one-to-one property, to solve for Given an exponential equation with unlike bases, use the one-to-one property to solve it. Rewrite each side in the equation as a power with a common base. If not, how can we tell if there is a solution during the problem-solving process? Recall that the range of an exponential function is always positive. While solving the equation, we may obtain an expression that is undefined. There is no real value of that will make the equation a true statement because any power of a positive number is positive. Analysis Figure shows that the two graphs do not cross so the left side is never equal to the right side.

    Thus the equation has no solution. Solve The equation has no solution. Solving Exponential Equations Using Logarithms Sometimes the terms of an exponential equation cannot be rewritten with a common base. In these cases, we solve by taking the logarithm of each side. Recall, since is equivalent to we may apply logarithms with the same base on both sides of an exponential equation. Given an exponential equation in which a common base cannot be found, solve for the unknown. Apply the logarithm of both sides of the equation. If one of the terms in the equation has base 10, use the common logarithm. If none of the terms in the equation has base 10, use the natural logarithm. Use the rules of logarithms to solve for the unknown.
