How does the first line go into Lojban?
Is it: {ca'e li pa du li no y'ybu}? Something
else?


Somewhat hard to say, since, as you note, nobody knows just how MEX works and this, as a point about the language of mthematics, would naturally go into MEX.  It certainly would not be your suggestions, since that makes no sense, being about a couple of numbers (and so not definable) and a letter (not obviously related to anything at all).  Maybe {ce'a pabu cu basti nobu ce'o y'ybu}

That's the Cowan place structure, yes. One problem is that
nobody quite knows how to put "ma'o e^x (where x is a
bound variable representing the argument)" into Lojban.
And if this is just a text then there is a second problem,
because it is not the text but the meaning of that text
that is of interest here.>

This is not obvious, it depends upon what the purpose of the sentence is.  Cherlin wants it to be a definition, and thus it is exactly text that is wanted, needed, possible.
