[tex]y=12^x\to y^{-1}=\log_{12}x;\ x\in\mathbb{R^+}\to\ y^{-1}=\dfrac{\log x}{\log12};\ x\in\mathbb{R^+}\to y^{-1}=\dfrac{\ln x}{\ln 12}[/tex]

Answer:

[tex] y = \dfrac{\log x}{\log 12} [/tex]

Step-by-step explanation:

[tex] y = 12^x [/tex]

[tex] x = 12^y [/tex]

[tex] \log x = \log 12^y [/tex]

[tex] \log x = y \log 12 [/tex]

[tex] y \log 12 = \log x [/tex]

[tex] y = \dfrac{\log x}{\log 12} [/tex]
