- Let 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_forward31. Prove statement of Theorem : for all integers and .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
- Use generalized induction and Exercise 43 to prove that n22n for all integers n5. (In connection with this result, see the discussion of counterexamples in the Appendix.) 1+2n2n for all integers n3arrow_forwardIn Exercise , use generalized induction to prove the given statement. for all integersarrow_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
- Let 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_forwardProve the half of Theorem 3.3 (e) that was not proved in the text.arrow_forward49. a. The binomial coefficients are defined in Exercise of Section. Use induction on to prove that if is a prime integer, then is a factor of for . (From Exercise of Section, it is known that is an integer.) b. Use induction on to prove that if is a prime integer, then is a factor of .arrow_forward
