WitrynaI have to prove that √5 is irrational. Proceeding 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. ⇒ p2 q2 = 5. ⇒ p2 = 5q2. This means that 5 divides p2. WitrynaFirst, we will assume that the square root of 5 is a rational number. Next, we will show that our assumption leads to a contradiction. Let us assume √5 is a rational number. Statement A 5 =yx y =0 such that yx is in its lowest form (there is no common factor of x and y). 5 =yx 5=y2x2 (Squaring both sides) 5y2 = x2 or x2 = 5y2 Equation 1 Statement B

WitrynaOh no, there is always an odd exponent. So 2 could not have been made by squaring a rational number! So its square root must be irrational.

Witryna4 lut 2015 · You can prove that 5 is not rational. Suppose, without lost of generality that there exists natural numbers $p, q$ such that: $$\sqrt5 =p/q$$ $$5q^2 = p^2$$ Then, $p$ has to be multiple of 5, so $p=5 k$. Therefore: $$q^2=5k^2$$ So $p, q$ cannot be relatively prime. $\sqrt 5$ cannot be expressed as a ratio of integers, so it is irrational. … acc全速域自适应巡航系统
