Umm, no comment.
Who wrote that in a book?
Apparently someone... lol I've found sometimes, search "words" from the Captcha's and you'll find Google books has the book/document it was written in. There tends to be only one. Also, most of the time I've noticed a pattern... There's usually a real word, and then gibberish, or vice versa. Maybe the real word is used and known by the system, and the other one is needed to help digitize the document it was from. Otherwise, I don't know how it could fend against bots.
Edit: Ithavati is a sanscrit word (or something) to mean minute or atomic... wtf See:

this newspaper if anyone wants to find it.
EditEditEdit: Probably not the newspaper, because I found it, and it clearly is xth avenue. x being unreadable. It does appear to look like "ith avati" but in context and the few letters after the supposed "avati" make it be some numbered avenue.
As for the really odd, almost mathematical formula... I don't even.
