I'm not sure if it is even possible to define the square root without first defining the absolute value. You need Intermediate Value Theorem and the definition of continuity. --barto (talk) 08:44, 2 August 2017 (EDT)

There's a good reason why both Smith and Binmore mention this in an exercise and a remark respectively, rather than taking it as the definition. --barto (talk) 09:00, 2 August 2017 (EDT)

Done, only Equivalence of Definitions of Absolute Value Function remains to be deleted/moved --barto (talk) (contribs) 15:47, 16 November 2017 (EST)
