Which Exponential Equation Is Equivalent To This Logarithmic Equation

The Relationship Between Exponential and Logarithmic Equations

Exponential and logarithmic equations are two sides of the same coin. They are inverse operations of each other, and understanding their relationship is crucial in solving mathematical problems. In this article, we will explore the concept of converting logarithmic equations into exponential form and vice versa, and discuss how to determine which exponential equation is equivalent to a given logarithmic equation.

Understanding Logarithmic Equations

Logarithmic equations are a way to express the relationship between the exponent and the base in an exponential equation. The general form of a logarithmic equation is:

log_b(x) = y

Where b is the base, x is the argument, and y is the exponent. The logarithm is the exponent to which the base must be raised to produce the argument. For example, in the equation log₂(8) = 3, the logarithm base is 2, the argument is 8, and the exponent is 3.

Converting Logarithmic Equations to Exponential Form

Converting a logarithmic equation into exponential form involves recognizing the relationship between the logarithmic equation and its equivalent exponential equation. The process of conversion can be summarized as follows:

1. Identify the base, the logarithm, and the argument in the logarithmic equation.
2. Rewrite the equation in exponential form, keeping the base, the logarithm, and the argument in the same positions.
3. The resulting exponential equation is the equivalent of the original logarithmic equation.

Examples of Converting Logarithmic Equations to Exponential Form

Let’s consider a few examples to illustrate the process of converting logarithmic equations to exponential form:

Example 1: Convert the logarithmic equation log₃(27) = 3 to exponential form.

In this equation, the base is 3, the logarithm is 3, and the argument is 27. To convert it to exponential form, we rewrite it as 3³ = 27. Therefore, the equivalent exponential equation is 3³ = 27.

Example 2: Convert the logarithmic equation log₄(64) = 3 to exponential form.

In this equation, the base is 4, the logarithm is 3, and the argument is 64. Converting it to exponential form yields 4³ = 64. Thus, the equivalent exponential equation is 4³ = 64.
