I think there is a mistake In Chapter 3, Exersice Set 3.2, Question 34 (a).
PDF solution: If n is not divisible by any prime number from 2 through √n, then n is not prime.
My Solution: If n is divisible by any prime number from 2 through √n, then n is not prime.
Which is right?

You are correct; this was fixed just recently so you might want to get the latest release.

Is 3.3.41(g) question incorrect?

[spamegg1]

I don't think so, why is it incorrect? Can you explain?

You have it as $\exists x \in \mathbb{R}$ such that $\forall y \in \mathbb{R}$, $y < x$ (Epp.tex#9181). In the book the question is $\forall x \in \mathbb{R}^+, \exists y \in \mathbb{R}^+$ such that $y<x$.
