Short Answer

Expert verified

The obtained result is 3.

Step by step solution

Step 1. Given information.

Consider the given expression.

$\log_{2} 4 路 \log_{4} 6 路 \log_{6} 8$

Step 2. Calculation.

Apply the base change formula to simplify the expression.

$\begin{array}{rcl} \log_{2} 4 路 \log_{4} 6 路 \log_{6} 8 & = & \frac{\log 4}{\log 2} 路 \frac{\log 6}{\log 4} 路 \frac{\log 8}{\log 6} \\ = & \frac{1}{\log 2} 路 \frac{1}{1} 路 \frac{\log 2^{8}}{1} \\ = & \frac{3 \log 2}{\log 2} \\ = & 3 \end{array}$
