- 30. Prove statement of Theorem : for all integers .arrow_forwardFind all monic irreducible polynomials of degree 2 over Z3.arrow_forwardAssume the statement from Exercise 30 in section 2.1 that for all and in . Use this assumption and mathematical induction to prove that for all positive integers and arbitrary integers .arrow_forward
- 31. Prove statement of Theorem : for all integers and .arrow_forwardIn the congruences ax b (mod n) in Exercises 40-53, a and n may not be relatively prime. Use the results in Exercises 38 and 39 to determine whether these are solutions. If there are, find d incongruent solutions modulo n. 42x + 67 23 (mod 74)arrow_forwardLet be integers, and let be positive integers. Use induction to prove the statements in Exercises . ( The definitions of and are given before Theorem in Section .) 18.arrow_forward
- 30. Prove that any positive integer is congruent to its units digit modulo .arrow_forwardLet xandy be integers, and let mandn be positive integers. Use induction to prove the statements in Exercises 1823. ( The definitions of xn and nx are given before Theorem 2.5 in Section 2.1.) xmxn=xm+narrow_forwardLet xandy be integers, and let mandn be positive integers. Use induction to prove the statements in Exercises 1823. ( The definitions of xn and nx are given before Theorem 2.5 in Section 2.1.) (xm)n=xmnarrow_forward
