WebMathematics 220, Spring 2024 Homework 11 Problem 1. Prove each of the following. 1. The number 3 √ 2 is not a rational number. Solution We use proof by contradiction. Suppose 3 √ 2 is rational. Then we can write 3 √ 2 = a b where a, b ∈ Z, b > 0 with gcd(a, b) = 1. We have 3 √ 2 = a b 2 = a 3 b 3 2 b 3 = a 3. So a 3 is even.

rationalise the denominator. 1/√6+√5-√11 - Brainly.in

WebBelow are the steps to perform rationalisation on denominators containing two terms. Step 1: Multiply both the numerator and the denominator by the denominator’s conjugate. Step 2: Distribute or use the FOIL technique for both the numerator and the denominator. Web1) Reduce the fraction: 12/(6√13) = 2/√13 2) Rationalize the denominator by creating a perfect square. Multiply by √13/√13 2/√13 * √13/√13 = 2√13 / 13 Hope this helps.
