Use mathematical induction to prove that 11!+22!++nn! = (n+1)!1, whenever n is a positive integer.
Use mathematical induction to prove that 3n < n! if n is an integer greater than 6. Problem 3Use mathematical induction to prove that 6 divides n3 n whenever n is a non- negative integer.Use mathematical induction to prove that 21 divides 4n+1 + 52n1 whenever n is a positive integer.Copyright By Assignmentchef assignmentchef

Use strong induction to show that every positive integer can be written as a sum of distinct powers of two, that is, as a sum of a subset of the integers 20 = 1, 21 = 2, 22 =4,andsoon.

Let b be a fixed integer and j a fixed positive integer. Show that if P (b), P (b + 1), , P(b+j) are true and [P(b)P(b+1)P(k)] P(k+1) is true for every integer k b + j, then P(n) is true for all integers n with n b.
Find the flaw with the following proof that an = 1 for all nonnegative integers n, whenever a is a nonzero real number.
Basis Step: a0 = 1 is true by the definition of a0.
Inductive Step: Assume that aj = 1 for all nonnegative integers j with j k. Then
ak+1=akak =11=1.
