Precalculus Version 4 - Algebra Review.

Guido
Hi,

I'm having a little problem with definition A.8 (the principal nth root).
The way it is formulated, the definiendum appears literally in the definiens.
I wonder if it wouldn't be better to go " the principal nth root of a, denoted so and so, is the unique real number b such that b to the power etc..."

In definition A.3 (subset) the connective 'if' is used where one would expect 'if and only if'.

That's nitpicking.
Please tell me to shut up.

It's not nit-picking!

On the contrary, I appreciate the careful reading of our book!

I'll pass these along to Jeffrey so when (if?) we get to editing this, we can revisit these comments!
