    \[\left( \sqrt[4]{6} \right)^{12x-4}=36^{x+4}\] Is this correct?

    you do know \[\sqrt[4]{6}= 6^{\frac{1}{4}}\]

    you also know the general rule \[ (a^b)^c = a^{bc} \]

    so let's use both ideas. replace fourth root of 6 with 6^(1/4) \[ (6^{\frac{1}{4}})^{12x-4} = 6^{\frac{12x-4}{4} }\]

    Yeah I think so, and it comes out to be x=9 correct?

    yes if we equate \[ 6^{3x-1} = 6^{2(x+4)} \] then the exponents must be equal 3x-1= 2x+8 x= 9
