sider the Mowing inductive definition of a version ofAekermann's function.This function was named after ttilhelm Ackerniann, a German
mathematician who was a student of the great mathematician David Hilbert. Aekermann's function plays an important role in the theory of recursive functions
and in the study of the complexity of certain algorithms involving set unions. [There are several different variants of this function. All are called Aekermann's
function and have similar properties even though their values do not always agree.)
Exercises 50-57 involve this version of Aekermann's function.

- (a) Consider the set A = {x R x has a terminating decimal expression}. Is A countable or uncountable? Give a one-sentence justification for your answer. You can use results from the chapter notes. (b) Recall the definition of |A|=|B| for sets A and B, and use the definition to show that |N| = |{/12/2 2}\. You do not need to prove that the function you define is a bijection. : ne z}|arrow_forwardConsider a function machine that accepts inputs as ordered pairs.

Rosen defines greatest integer function: The greatest integer function in a real number x, denoted by [x], is the largest integer less than or equal to x. That is [x] is an integer satisfying: [x] ≤ x < [x]+1 Kenneth H. Rosen also defines below: The fractional part of a real number x, denoted by {x}, is the difference between x and the largest integer less than or equal to x, namely [x]. That is, {x}=x-[x]. I want to use these definitions to answer the following: Chapter 1.1, Exercise 13: Show that [x+y] ≥ [x] + [y] for all real numbers x and y.arrow_forward
