$( \frac{1}{36} )^{-y^2}=6^{2x+4} \\ \\ 
(6^{-2})^{-y^2}=6^{2x+4} \\ \\ 
6^{2y^2}=6^{2x+4} \\ \\ 
2y^2=2x+4 \\ 
2y^2=2(x+2) \\ 
y^2=x+2$

ОДЗ: x+1>0
x> -1
$log_{4}(2y^2-2x+4)=6^{log_{6}(3lg \sqrt[3]{10} )}+log_{4}(x+1) \\ \\ 
log_{4}(2y^2-2x+4)=3lg \sqrt[3]{10}+log_{4}(x+1) \\ \\ 
log_{4}(2y^2-2x+4)=lg( \sqrt[3]{10} )^3+log_{4}(x+1) \\ \\ 
log_{4}(2y^2-2x+4)=lg10+log_{4}(x+1) \\ \\ 
log_{4}(2y^2-2x+4)=1+log_{4}(x+1) \\ \\ 
log_{4}(2y^2-2x+4)=log_{4}4+log_{4}(x+1) \\ \\ 
log_{4}(2y^2-2x+4)=log_{4}(4(x+1))$
2y²-2x+4=4(x+1)
2y²-2x-4x=4-4
2y²-6x=0
y²-3x=0
y²=3x

{y²=x+2
{y²=3x

x+2=3x
x-3x=-2
-2x=-2
x=1

y²=3*1
y²=3
y₁=√3
y₂= -√3

Ответ: (1; -√3);
(1; √3).
