Let SCR be the set of algebraic numbers. Prove that S is countable. Hint: You may use the fact (which you might have seen in class or you can prove separa if I is a countable set and for each i, A; is a countable set then Uiel Ai is a countable set. Hint: You may also use the fact that a polynomial of degree n can have at most n real For Q4-5, suppose that A, B CR are nonempty and bounded from above. Prove that if ACB, then sup(A) ≤ sup(B). Define A + B = {a+b: a EA, b E B}. a) Determine {1, 3, 5} + {-3,0, 1}. b) Prove that sup (A + B) = sup(A) + sup(B). It is not easy to prove that a number is transcendental.
