Question 5Let m, n be two integers. For each of the statements below, decide if it is TRUE or FALSE:(a) If 9|mn, then 9|m or 9|n. [Select ](b) If 19|mn, then 19|m or 19|n.( Select ](c) If 19 mn, then 19|m and 19|n. [ Select ]>>

We know, a|b means, a divides b. Here 9| mn means 9 divides mn 19| mn means 19 divides mn. We have…

Determine whether the following statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. If set A is equivalent to the set of natural numbers that are multiples of 16, then n(A) = No. Choose the correct answer below. A. The statement is true. OB. The statement should be changed to "If set A is equivalent to the set of natural numbers that are multiples 1 of 16, then n(A)= No 16 C. The statement should be changed to "If set A is equivalent to the set of natural numbers that are multiples of 16, then n(A)
Suppose you want to refute the statement: There are some natural numbers a, b, and c where a | b and b | c but a does not divide c. Which of the following would be an appropriate strategy for you to employ? Group of answer choices Show specific values for a, b, and c where a | b and b | c and a | c. Show specific values for a, b, and c where a does not divide b and b does not divide c, but a | c. Show for any generic choices of a, b, and c that if a | b and b | c then a | c. Show for any generic choices of a, b, and c if a does not divide b and b does not divide c then a does not divide c.
