Solving Logarithmic Equations: A Step-by-Step Guide

=====================================================

Introduction

Logarithmic equations are a fundamental concept in mathematics, and solving them requires a clear understanding of the properties of logarithms. In this article, we will focus on solving the equation $\log_6 x = -1$ for the variable $x$ . We will break down the solution into manageable steps and provide a clear explanation of each step.

Understanding Logarithmic Equations

A logarithmic equation is an equation that involves a logarithm. The general form of a logarithmic equation is $\log_b x = y$ , where $b$ is the base of the logarithm, $x$ is the argument of the logarithm, and $y$ is the result of the logarithm. In this case, we have $\log_6 x = -1$ , where $6$ is the base of the logarithm, $x$ is the argument of the logarithm, and $-1$ is the result of the logarithm.

Properties of Logarithms

To solve the equation $\log_6 x = -1$ , we need to use the properties of logarithms. One of the most important properties of logarithms is the definition of a logarithm:

\log_b x = y \iff b^y = x

This property allows us to rewrite the equation $\log_6 x = -1$ as:

6^{-1} = x

Solving for x

Now that we have rewritten the equation, we can solve for $x$ . To do this, we need to evaluate the expression $6^{-1}$ .

6^{-1} = \frac{1}{6}

Therefore, the solution to the equation $\log_6 x = -1$ is:

x = \frac{1}{6}

Rounding to Two Decimal Places

Since the solution is a fraction, we need to round it to two decimal places. To do this, we can divide the numerator by the denominator:

\frac{1}{6} = 0.17

Therefore, the solution to the equation $\log_6 x = -1$ rounded to two decimal places is:

x = 0.17

Conclusion

In this article, we have solved the equation $\log_6 x = -1$ for the variable $x$ . We have used the properties of logarithms to rewrite the equation and then solved for $x$ . We have also rounded the solution to two decimal places. The solution to the equation is $x = 0.17$ .
