    Using the rules for logs: $$ y=\log_6{\sqrt 6}=\log_6{ 6^{1/2}}=\cfrac{1}{2}\log_6{ 6}=\cfrac{1}{2}\\ $$ Since \(\log_6{ 6}\) means, what is x such that \(6^x=6\). Therefore, x=1 and the result follows since \(\log_6{ 6}=1\) Does this make sense?

    Be careful, the rule is $$ \log a^{1/2}=(1/2)\log a $$
