 Author Comment/Response Bill Simpson 08/30/12 1:36pm Because you are terrible with mathematical notation I must guess what you might be wanting. Hopefully something in this will help you. In[1]:= Solve[5==x^2*y^2,{x,y}] Out[1]= {{x -> -(Sqrt[5]/y)}, {x -> Sqrt[5]/y}} In[2]:= Solve[1==x^2*y^2,{x,y}] Out[2]= {{x -> -y^(-1)}, {x -> y^(-1)}} In[3]:= Solve[1==x^2*y^2,{x,y}]/.y->{3,5,7} Out[3]= {{x -> {-1/3, -1/5, -1/7}}, {x -> {1/3, 1/5, 1/7}}} If that does not provide what you want then perhaps if you gave a few clear examples of what you would like to give Mathematica and what you would want it to return to you.
