36=2^2 3^2   36=36^1 =(±6)^2    ((x),(y) ) ∈{ (((−6)),(2) ) ,  ((6),(2) ) ,  (((36)),(1) )}

$$\mathrm{36}=\mathrm{2}^{\mathrm{2}} \mathrm{3}^{\mathrm{2}} \\ $$$$\mathrm{36}=\mathrm{36}^{\mathrm{1}} =\left(\pm\mathrm{6}\right)^{\mathrm{2}} \\ $$$$\begin{pmatrix}{{x}}\\{{y}}\end{pmatrix}\:\in\left\{\begin{pmatrix}{−\mathrm{6}}\\{\mathrm{2}}\end{pmatrix}\:,\:\begin{pmatrix}{\mathrm{6}}\\{\mathrm{2}}\end{pmatrix}\:,\:\begin{pmatrix}{\mathrm{36}}\\{\mathrm{1}}\end{pmatrix}\right\} \\ $$
