Transcript text: Use properties of logarithms to find the exact value of the expression. Do not use a calculator.
\[
\log _{6} 48-\log _{6} 8
\]
$\log _{6} 48-\log _{6} 8=$ $\square$ (Type an integer or a simplified fraction.)
Solution
Solution Steps
To solve the expression \(\log_{6} 48 - \log_{6} 8\), we can use the properties of logarithms. Specifically, we can use the property that \(\log_b (a) - \log_b (c) = \log_b \left(\frac{a}{c}\right)\). This allows us to combine the logarithms into a single logarithm.
Step 1: Apply the Logarithm Property
We start with the expression:
\[
\log_{6} 48 - \log_{6} 8
\]
Using the property of logarithms \(\log_b (a) - \log_b (c) = \log_b \left(\frac{a}{c}\right)\), we can combine the logarithms:
\[
\log_{6} 48 - \log_{6} 8 = \log_{6} \left(\frac{48}{8}\right)
\]
Step 2: Simplify the Fraction
Next, we simplify the fraction inside the logarithm:
\[
\frac{48}{8} = 6
\]
So the expression becomes:
\[
\log_{6} 6
\]
Step 3: Evaluate the Logarithm
We know that \(\log_b b = 1\) for any base \(b\). Therefore:
\[
\log_{6} 6 = 1
\]
