Maple Issues: Avoiding Unwanted Simplifications

For Maple-graded questions we commonly use printf(MathML:-ExportPresentation(expression)) to display the answer in a nice formatted manner. Unfortunately Mobius will perform simplification of expressions whether you want it or not. This happens most often with square roots. For example $\sqrt{\frac{12}{18}}$ which we want to display as $\sqrt{\frac{2}{3}}$ will display as $\frac{1}{3}\sqrt{6}$ because Mobius idiotically rationalizes the denominator.

Fortunately the algorithmic section's mathml command does this properly. For example

$X=mathml("sqrt(12/18)"); will display $X as $\sqrt{\frac{2}{3}}$. So instead of using the method above to display an answer "$Ans" define the MathML version in the algorithmic section:

$AnsML=mathml("$Ans");

then in the ANSWER field:

Note that the backquotes are necessary when displaying already-created MathML.
