Why doesn't this work in Geogebra I've got a really simple equation that I want GeoGebra to plot:
$\sqrt {2x}-\sqrt {3y} =2$
It says it's an illegal operation so I try:
$3y=2x-4\sqrt{2x}+4$
When this doesn't try, I try changing $\sqrt{2x}$ to $(2x)^{1/2}$ and it informs me that exponents can only be integers. Since when can't geogebra handle rational exponents?!

The original equation in this thread now plots correctly as well as several others that previously would not plot such as $\ \sin (x+y) = x/y \ $.  Even simple ones like $ \ \sin y = x \ $ would not plot a year ago and now work with no problem.  Nice work GeoGebra.
