5. (a). Find a counterexample to show that "n e Z, 12 + 9 + 61 is prime" is false. (b). Determine the truth value of “Vc € R+, In € Zt, 'n <c", and justify your answer.
i honestly just don't know where to start with these
4. Prove or find a counterexample for each: (a) If A and B are inductive, then AUB is inductive. (b) If A and B are inductive, then An B is inductive.
Prove or find a counterexample for the following. Assume that f (n) and g (n) are monotonically increasing functions that are always larger than 1. f (n) = o (g (n)) rightarrow log (f (n)) = o (log (g (n))) f (n) = O (g (n)) rightarrow log (f (n)) = O (log (g (n))) f (n) = o (g (n)) rightarrow 2^f (n) = o (2^g (n)) f (n) = O (g (n)) rightarrow 2^f (n) = O (2^g...
Prove or give a counterexample to the following statement: If the coefficient matrix of a system of m linear equations in n unknowns has rank m, then the system has a solution.
HELPPPP!!!! sepcific
explanation is best !!! this is discrete mathematics content.
1. Prove, or disprove by finding a counterexample: If a|bc where a,b and c are positive integers then a b or a c. 2. Let n be an odd integer. Show that there is an integer k such that n2 = 8k +1.
PLEASE use smallest
counterexample!
n(n+1) 1. Prove by smallest counterexample: 1 + 2 + . . . + n
Prove or give a counterexample: For any integers b and c and any positive integer m, if b ≡ c (mod m) then b + m ≡ c (mod m).
For each of the following statements, either prove the statement or give a counterexample that shows the statement is false. We will use the (non-standard) notation I to represent the irrational numbers Each problem is worth 10 points. 1. For all mEN2, m2-1 is composite. 2. For all integers a and b If ab is even then a is even or b is even. 3. For all integers a, b, and c If ale and ble then ablc
