can someone please answer my homework? thank you very much

4. Prove or disprove: For all subsets A and B of Z, if AUB = Z, then A = Z or B = Z. 5. Show that there is no integer whose square leaves a remainder of 3 when divided by 7. n2(n+ 1)² 6. Prove by induction that for all n EN, E³ 4 i=1 7. Show that for any x E Q' and any y E R, x + y E Q' or x – y E Q'. 8. Prove that for all a, b, and c € Z, if a ł (bc – 1), then n † (b+1) or n { (c +1). 9. Let {an}1 be a sequence. We say that {an}1 increases with bound, written lim a, = +∞, iff 100 (VM > 0)(3N > 0)(Vn E N)(n > N= an > M). Show that lim n = +0o.
