Use a completeness property of the real number system to show that 2 has a positive square root.

Use the Induction Theorem to show that for any natural number m, the sum m+n and the product mn are again natural for any natural number n. Thus N is closed under addition and multiplication, and consequently so is Z. (b) Which of the field axioms continue to hold for the natural numbers? (c) Which of the field axioms continue to hold for the integers?

Use the Intermediate Value Theorem to show that 2 has a positive square root.

Let f : [0, 1] −→ [0, 1] be continuous. Use the Intermediate Value Theorem to show that f(x) = x for some x ∈ [0, 1].

Let a and b be real numbers with a < b. Suppose that f : [a, b] −→ R is continuous and that f is differentiable on the open subinterval (a, b). Use the Mean Value Theorem to show that if f ′ > 0 on (a, b) then f is strictly increasing on [a, b].
