To proove root 3 is irrational no. |
|
Answer» Let us assume that √3 is a rational number.That is, we can find integers a and b (≠ 0) such that √3 = (a/b)Suppose a and b have a common factor other than 1, then we can divide by the common factor, and assume that a and b are coprime.√3b = a⇒\xa03b2=a2 (Squaring on both sides) → (1)Therefore, a2 is divisible by 3Hence ‘a’ is also divisible by 3.So, we can write a = 3c for some integer c.Equation (1) becomes,3b2 =(3c)2⇒\xa03b2 = 9c2∴ b2 = 3c2This means that b2 is divisible by 3, and so b is also divisible by 3.Therefore, a and b have at least 3 as a common factor.But this contradicts the fact that a and b are coprime.This contradiction has arisen because of our incorrect assumption that √3 is rational.So, we conclude that √3 is irrational.\xa0 It is prove same as root 2 |

Prove that if x and y are both odd positive integers then x2+y2 is even but not divisible by 4 |
| Answer» Since x and y are odd positive integers, Then it should be in the form of 2x+1 (where x is a positive integer)Let x = 2m + 1 and y = 2n + 1 ( where m and n positive integers)Now x2 + y2= (2m + 1)2 + (2n + 1)2= 4m2 + 4m + 1 + 4n2 + 4n + 1= 4(m2 + n2 + m + n) + 2 ....... (1)from (1) we getx2 + y2 = 2 {m2 + n2 + m + n) + 1} = 2t (t = 2(m2 + n2 + m + n) + 1 is a positive integerTherefore it is clear that {tex}x^2+y^2{/tex} is an even number but not divisible by 4. | |

Prove that /2 is a irrational number ..???Koi h jo isse easy way me bta skta ..???? |
|
Answer» Thnx dear? Let /2 be the rational noSo it will in the form of a/b = /2Now there are no common factors between "a and b" a/b =/2a = /2bDo square on both side(a)^2 =(/2b)^2a^2 = 2b^2 ••••••••••••••••••eq 1Now according to theorem 2 will divide a^2 and 2 will divide aNow , let a = 2mDo square on both side(a)^2 = ( 2m)^2a^2= 4m^2 ••••••••••••••••••••eq2Now from eq 1 and 22b^2 =4m^2b^2 = 4m^2 /2b^2 = 2m^2Now again according to theorem 2 will divide b^2 and 2 will divide b #there are common factor between a" and bTherfore it contradicts to our asumption that /2 is rational # /2 is irrational Hence proved If you liked answer then please give the vote ♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡ |
