Answer:
A. The solution set is {4096}.
Explanation:
Given the logarithmic equation:

Multiply both sides of the equation by 2:

Next, apply the power law of logarithms to the right side of the equation.
![\begin{gathered} \log_6x=\log_64^6 \\ \implies\operatorname{\log}_6x=\operatorname{\log}_64096 \end{gathered}]()
Since the bases are the same, equate the numbers:

The solution set is {4096}.
