Chapter 5: Q 20. (page 308)

Use properties of logarithms to find the exact value of each expression. Do not use a calculator.
$\log_{6} 9 + \log_{6} 4$

Short Answer

Expert verified

The obtained value is 2.

Step by step solution

Step 1. Given information.

Consider the given information.

$\log_{6} 9 + \log_{6} 4$

Step 2. Logarithm properties.

The properties are defined as,

$\begin{array}{l} \log_{a} a = 1 \\ \log (M N) = \log_{a} M + \log_{a} N \\ \log_{a} M^{r} = r \log_{a} M \end{array}$

Step 3. Calculation.

Apply the properties.

$\begin{array}{rcl} \log_{6} 9 + \log_{6} 4 & = & \log_{6} (9 \times 4) \\ = & \log_{6} 36 \\ = & \log_{6} 6^{2} \\ = & 2 \log_{6} 6 \\ = & 2 \end{array}$
