You have a … Webb1 Answer. Let us assume, to the contrary, that √2 is rational. So, we can find integers a and b such that √2 = a/b where a and b are coprime. So, b √2 = a. Squaring both sides, we get 2b2 = a2. Therefore, 2 divides a2 and so 2 divides a. Substituting for a, we get 2b2 = 4c2, that is, b2 = 2c2. Therefore, a and b have at least 2 as a ... navisworks a che serve

Here it is: remember that to say that a number is rational is to say that it is a / b, where a and b are integers (e.g. 5 / 7, etc.). So suppose log 2 3 = a / b. Since this is a positive number, we can take a and b to be positive. Then 2 a / b = 3. 2 a = 3 b. market town fire 1723
