y=log_6 x⇒x=6^y   6^y^2  +(6^y )^y =12⇒2×6^y^2  =12⇒6^y^2  =6⇒  y^2 =1⇒y=±1  if y=1⇒log_6 x=1⇒x=6  if y=−1⇒log_6 x=−1⇒x=6^(−1) =(1/6)
$${y}={log}_{\mathrm{6}} {x}\Rightarrow{x}=\mathrm{6}^{{y}} \\ $$$$\mathrm{6}^{{y}^{\mathrm{2}} } +\left(\mathrm{6}^{{y}} \right)^{{y}} =\mathrm{12}\Rightarrow\mathrm{2}×\mathrm{6}^{{y}^{\mathrm{2}} } =\mathrm{12}\Rightarrow\mathrm{6}^{{y}^{\mathrm{2}} } =\mathrm{6}\Rightarrow \\ $$$${y}^{\mathrm{2}} =\mathrm{1}\Rightarrow{y}=\pm\mathrm{1} \\ $$$${if}\:{y}=\mathrm{1}\Rightarrow{log}_{\mathrm{6}} {x}=\mathrm{1}\Rightarrow{x}=\mathrm{6} \\ $$$${if}\:{y}=−\mathrm{1}\Rightarrow{log}_{\mathrm{6}} {x}=−\mathrm{1}\Rightarrow{x}=\mathrm{6}^{−\mathrm{1}} =\frac{\mathrm{1}}{\mathrm{6}} \\ $$
