Prove that root 2 plus root 5 is irrational

Webb28 feb. 2015 · Consider this, Prove that 2 is irrational. Assume 2 = m / n then, suppose m is odd, n is even (without loss of generality), and gcd ( m, n) = 1 and m, n are integers. Since m was odd, m 2 is odd, but since n is even, 2 n 2 is also even. So m is both odd an even, a contradiction. Then, since 1 is rational. Webbsqrt 5^2 If an irrational is taken to any root , for example, sqrt 5^2, if we raise it to the second power, it can be rational. Thus, the the sq root of 5 (which is really raised to the …

WebbSolution. Let √3+√5 be a rational number. A rational number can be written in the form of p/q where p,q are integers. p,q are integers then (p²+2q²)/2pq is a rational number. Then √5 is also a rational number. But this contradicts the fact that √5 is an irrational number. So,our supposition is false.

WebbProceeding as in the proof of 2, let us assume that 5 is rational. This means for some distinct integers p and q having no common factor other than 1, p q = 5 ⇒ p 2 q 2 = 5 ⇒ p 2 = 5 q 2 This means that 5 divides p 2. This means that 5 divides p (because every factor must appear twice for the square to exist). WebbA corollary of this is that $2^{\sqrt{2}}$ is transcendental, and so is its square root $\sqrt{2}^{\sqrt{2}}$. The outlines of both Gelfond and Kuzmin's constructive proof can be found here . As David Mitra pointed out the comments, Niven's book had a section dedicated to this.

Webb17 juni 2015 · Let √2 + √3 = (a/b) is a rational no. On squaring both sides , we get 2 + 3 + 2√6 = (a 2 /b 2) So,5 + 2√6 = (a 2 /b 2) a rational no. So, 2√6 = (a 2 /b 2) – 5 Since, 2√6 is an irrational no. and (a 2 /b 2) – 5 is a rational no. So, my contradiction is wrong. So, (√2 + √3) is an irrational no.
