Self-checking with radicals

Questions

Fairly easy (maybe not simple) if you aren’t randomizing anything. So \sqrt{48} for example:
In the math input CL:

check= this.numericValue<=6.93 and this.numericValue>6.92 
and countNumberUsage(this.latex,4)=1 and countNumberUsage(this.latex,3)=1
correct: check

First line checks that it’s the correct value (I’m using a range because it’s a non-terminating decimal). Second checks that the number 4 occurs once and 3 occurs once. You can use the same strategy for fraction forms.
Then, in your note CL:

feedback= when not(inputName.submitted) ""
          when inputName.script.check "Correct text"
          otherwise "Incorrect text"

Then (not in the CL), click the {#} button to insert “feedback” into your note text.
