Understanding the Relationship Between Logarithms and Exponents

In mathematics, logarithms and exponents are two closely related concepts that are often used interchangeably. A logarithm is the power to which a base number must be raised to produce a given value, while an exponent is the power to which a base number is raised to produce a given value. In this article, we will explore how to express a logarithmic equation in exponential form, using the given equation $\log_{32} 2 = \frac{1}{5}$ as an example.

Expressing the Equation in Exponential Form

To express the equation $\log_{32} 2 = \frac{1}{5}$ in exponential form, we need to rewrite it in the form $A^B = C$ . Here, $A$ is the base number, $B$ is the exponent, and $C$ is the result of raising the base number to the power of the exponent.

Finding the Base Number (A)

The base number is the number that is being raised to a power to produce the given value. In this case, the base number is 32.

Finding the Exponent (B)

The exponent is the power to which the base number is raised to produce the given value. In this case, the exponent is $\frac{1}{5}$ .

Finding the Result (C)

The result is the value that is produced by raising the base number to the power of the exponent. In this case, the result is 2.

Rewriting the Equation in Exponential Form

Now that we have identified the base number, exponent, and result, we can rewrite the equation in exponential form as follows:

$32^{\frac{1}{5}} = 2$

Understanding the Relationship Between the Base Number and the Exponent

In this equation, the base number is 32 and the exponent is $\frac{1}{5}$ . This means that 32 raised to the power of $\frac{1}{5}$ is equal to 2.

Simplifying the Exponent

The exponent $\frac{1}{5}$ can be simplified by raising 32 to the power of 5 and then taking the fifth root of the result.

$32^{\frac{1}{5}} = \sqrt[5]{32^5}$

Evaluating the Result

Now that we have simplified the exponent, we can evaluate the result by raising 32 to the power of 5 and then taking the fifth root of the result.

$\sqrt[5]{32^5} = 2$

Conclusion

In this article, we have explored how to express a logarithmic equation in exponential form using the given equation $\log_{32} 2 = \frac{1}{5}$ as an example. We have identified the base number, exponent, and result, and rewritten the equation in exponential form as $32^{\frac{1}{5}} = 2$ . We have also simplified the exponent and evaluated the result to demonstrate the relationship between the base number and the exponent.
