In the realm of mathematics, logarithms serve as powerful tools for simplifying complex calculations and unraveling exponential relationships. A logarithm, at its core, represents the exponent to which a base must be raised to produce a specific number. Understanding the properties of logarithms is essential for manipulating logarithmic expressions and solving equations involving logarithms. In this article, we will delve into the intricacies of expressing logarithmic expressions as a single logarithm, focusing on the expression 6 log_b(q) - log_b(r) and illustrating the step-by-step process involved.

Understanding Logarithmic Properties

Before we embark on the journey of condensing logarithmic expressions, it's crucial to grasp the fundamental properties that govern their behavior. These properties serve as the building blocks for manipulating and simplifying logarithmic expressions. Let's explore some of these key properties:

  • Product Rule: The logarithm of a product is equal to the sum of the logarithms of the individual factors. Mathematically, this is expressed as log_b(xy) = log_b(x) + log_b(y).
  • Quotient Rule: The logarithm of a quotient is equal to the difference of the logarithms of the numerator and denominator. This can be represented as log_b(x/y) = log_b(x) - log_b(y).
  • Power Rule: The logarithm of a number raised to a power is equal to the product of the power and the logarithm of the number. Mathematically, this is written as log_b(x^p) = p log_b(x).

With these properties in our arsenal, we can effectively manipulate logarithmic expressions and express them in more concise forms.

Applying the Power Rule

Our initial expression, 6 log_b(q) - log_b(r), presents an opportunity to apply the power rule. The power rule states that log_b(x^p) = p log_b(x). In our expression, the term 6 log_b(q) can be rewritten using the power rule. We can bring the coefficient 6 inside the logarithm as an exponent of q, transforming the term into log_b(q^6). This step effectively condenses the expression by eliminating the coefficient.

Now, our expression takes the form log_b(q^6) - log_b(r). This transformation sets the stage for the next step, where we'll utilize the quotient rule to further simplify the expression.

Utilizing the Quotient Rule

With the power rule successfully applied, our expression stands as log_b(q^6) - log_b(r). The quotient rule comes into play here, which states that log_b(x/y) = log_b(x) - log_b(y). This rule allows us to combine two logarithms with the same base that are being subtracted. In our expression, we have the difference of two logarithms with the base b. Applying the quotient rule, we can rewrite the expression as a single logarithm of a quotient.

The quotient is formed by placing the argument of the first logarithm (q^6) in the numerator and the argument of the second logarithm (r) in the denominator. This transformation yields the expression log_b(q^6 / r). This single logarithm encapsulates the original expression, showcasing the power of logarithmic properties in simplifying mathematical expressions.

Expressing as a Single Logarithm: 6 log_b(q) - log_b(r) = log_b(q^6/r)

Having navigated through the application of the power rule and the quotient rule, we arrive at the culmination of our efforts: expressing the original expression as a single logarithm. The expression 6 log_b(q) - log_b(r) has been successfully transformed into the single logarithm log_b(q^6/r).

This transformation not only simplifies the expression but also provides a more concise representation of the underlying mathematical relationship. The single logarithm encapsulates the combined effect of the initial logarithmic terms, offering a clear and efficient way to express the relationship between q, r, and the base b.

In summary, to express 6 log_b(q) - log_b(r) as a single logarithm, we first apply the power rule to rewrite 6 log_b(q) as log_b(q^6). Then, we use the quotient rule to combine the two logarithms into a single logarithm, resulting in log_b(q^6/r). This final expression represents the single logarithmic form of the original expression.
