by the way: utf8 is the default for years, you do not need to load inputenc

This is not a useful description of the problem. What does "won't work" 
exactly mean??
I have no problem with

\psplot[plotpoints=200, algebraic=true]{\xmin}{10.4}{x*x}
\psplot[plotpoints=200, algebraic,linecolor=red]{\xmin}{10.4}{x^2}
\psplot[plotpoints=200, algebraic=false,linecolor=blue]{\xmin}{10.4}{x 2 
exp}
