Proof: An nth root of 2 is, by definition, a root of the polynomial: f(x) = xn−2 But the only possible rational roots of f(x) are 1,−1,2,−2 by the test. Since none of these solve xn−2 = 0, we see that n √ 2 isn’t rational! Amusing Observation: This is our third ...

Webb6 nov. 2024 · When applying Descartes’ rule, we count roots of multiplicity k as k roots. For example, given x 2 −2x+1=0, the polynomial x 2 −2x+1 has two variations of the sign, and hence the equation has either two positive real roots or none. The factored form of the equation is (x−1) 2 =0, and thus 1 is a root of multiplicity 2. To illustrate the variety of … WebbSolution for Given that loga b = 12/1/2 x² and log √a = 3' evaluate X.
