This is a discrete math question: Exercise 5. Let A and B be sets. Prove or disprove: AAB| = |A - B+B - AL. Claim. Proof
Discrete Math A Criterion for Divisibility by 3. Prove that a number is divisible by 3 if the sum of its digits (when written in base 10) is divisible by 3. Again, it will help to remember what decimal notation means.
Discrete Math: Prove that there can be no perfect square between 25 and 36, i.e. there is no integer n so that 25 < n2 < 36. Prove this by directly proving the negation. Your proof must only use integers, inequalities and elementary logic. You may use that inequalities are prsered by adding a number on both sides, or by multiplying both sides by a positive number. You cannot use the square root function. Do not write a proof by...

Discrete Math: Divisibility (Need Help ASAP, will upvote) 1) Prove that if n is an odd positive integer, then n^2 is congruent to 1 (mod 8)
Please answer this discrete math question 1. Prove that 1522 - 1 is a multiple of 46. (HINT: Do NOT multiply 15 by itself 22 times! Just have a look at item 14 in the notes.)
Discrete Math Use mathematical induction to prove that for all positive integers n, 2 + 4 + ... + (2n) = n(n+1).
Discrete Math Use division into two cases to prove that for every integer n, 2\n(3n + 1).
