4. Use a proof by contradiction to show that the square root of 3 is irrational. You may use the following fact: For any integer k, if k2 is a multiple of 3, then k is a multiple of 3. Hint: The proof is very similar to the proof that √2 is irrational.

5. Use a direct proof to show that the product of a rational number and an integer must be a rational number.

6. Use a proof by contradiction to show that the sum of an integer and an irrational number must be irrational.

Contradiction proof conception Prove: If A is true, then B is true Contradiction: If A is true, then B is false. so we suppose B is false and follow the step to prove. At the end we get if A is true then B is true so contradict our assumption However, Theorem: Let (xn) be a sequence in R. Let L∈R. If every subsequence of (xn) has a further subsequence that converges to L, then (xn) converges to L. Proof: Assume,...

For each of the statements, begin a proof by contraposition and a proof by contradiction. This will include rewriting the statement, writing the assumptions, and writing what needs to be shown. From there, pick one of the two methods and finish the proof. a) For all integers m and n, if m + n is even the m and n are both even or m and n are both odd. b) For all integers a, b, and c, if a...

write a function to determine the square root of a number. The square root of a number can be approximated by repeated calculation using the formula NG = 0.5(LG + N/LG) where NG stands for the next guess and LG stands for the last guess. The loop should repeat until the difference between NG and LG is less than 0.00001. Use an initial guess of 1.0. Write a driver program to test your square root function. I WANT THIS PROGRAM...
