Understanding Logarithmic and Exponential Statements

In mathematics, logarithmic and exponential statements are two sides of the same coin. While logarithmic statements express a quantity as the power to which a base number must be raised to obtain a given value, exponential statements express a quantity as the result of raising a base number to a given power. In this article, we will explore how to convert logarithmic statements to their equivalent exponential forms.

The Relationship Between Logarithmic and Exponential Statements

The relationship between logarithmic and exponential statements is based on the fact that they are inverse operations. This means that if we have a logarithmic statement of the form $\log_b(x) = y$ , then its equivalent exponential statement is $b^y = x$ . Conversely, if we have an exponential statement of the form $b^x = y$ , then its equivalent logarithmic statement is $\log_b(y) = x$ .

Converting Logarithmic Statements to Exponential Equivalents

To convert a logarithmic statement to its equivalent exponential form, we need to use the following formula:

b^{\log_b(x)} = x

This formula tells us that if we have a logarithmic statement of the form $\log_b(x) = y$ , then its equivalent exponential statement is $b^y = x$ .

Example 1: Converting a Logarithmic Statement to an Exponential Equivalent

Let's consider the following logarithmic statement:

\log_3\left(\frac{1}{9}\right) = -2

To convert this statement to its equivalent exponential form, we can use the formula above. We have:

b = 3, x = \frac{1}{9}, y = -2

Substituting these values into the formula, we get:

3^{-2} = \frac{1}{9}

This is the equivalent exponential statement of the original logarithmic statement.

Example 2: Converting a Logarithmic Statement to an Exponential Equivalent

Let's consider the following logarithmic statement:

\log_5(25) = 2

To convert this statement to its equivalent exponential form, we can use the formula above. We have:

b = 5, x = 25, y = 2

Substituting these values into the formula, we get:

5^2 = 25

This is the equivalent exponential statement of the original logarithmic statement.

Example 3: Converting a Logarithmic Statement to an Exponential Equivalent

Let's consider the following logarithmic statement:

\log_2(8) = 3

To convert this statement to its equivalent exponential form, we can use the formula above. We have:

b = 2, x = 8, y = 3

Substituting these values into the formula, we get:

2^3 = 8

This is the equivalent exponential statement of the original logarithmic statement.
