    जब टूटने लगे हौंसला तो इतना याद रखना की,

    ढूंढ लेते है जुगनू अंधेरो में भी मंजिल,
    क्यूंकि वो कभी रौशनी के मोहताज नहीं होते !!

    Let us assume that √3 is a rational no.
    Now, Let √3=a/b where a and b are co-prime and b is not equals to 0
    Squaring both sides
    (√3)²=(a/b)²
    3 =a²/b²
    3b²=a²
    b²=a²/3
    a² is divisible by 3
    a is also divisible by 3
    Let, a=3m for some integer m.
    √3=3m/b
    Squaring both sides
    (√3)²=(3m/b)²
    3=9m²/b²
    3b²=9m²
    b²=9m²/3
    b²=3m²
    b²\3=m²
    b² is divisible by 3
    b is also divisible by 3
    So, Our assumption that a and b are co prime is wrong.
    So, √3 is a irrational no.

    Sir home work
    Q- proof √3 irrational ?
    Ans-Let assume that √3 is rational and co-prime we can write√3 as p/q form were q is not equal to 0
    √3=a/b
    Squaring both side
    (√3)²=a²/b²
    3=a²/b²
    3b²=a²
    b²=a²/3
    3 is divisible by a²
    3 is also divisible by a
    Let a = 3k
    √3 = 3k/b
    Now,squaring both side
    (√3)² = (3k)²/b²
    3 = 9k²/b²
    3b²=9k²
    b²=9k²/3
    b²=3k²
    b²/3=k²
    3 is divisible by b²
    3is also divisible by b
    The situation is contradiction
    Our assumption is wrong
    Hens,√3 is irrational number

    Assume that √5 is a rational number
    So,it can be written as √5=p/q were q ≠0
    And p and w are co prime
    Squaring both side••
    (√5)²=(p/q)²
    5=p²/q²
    Next,q²5=p²
    q²=p²/5
    P² is divisible by 5
    So,P IS ALSO DIVISIBLE BY 5
    Let P = 5m for some integers
    Put the value••
    √5=5m/q
    Squaring both side
    (√5)²=(5m/q)²
    Root cancellation
    5=5m²/q²
    5=25m²/q²
    q²5=25m²
    q²=5m
    q²/5=m²
    SO q² IS DIVISIBLE BY
    Hence q is also divisible by five,it proves our assumption wrong
    So √5 is irrational

      Solve- let 6+√2 is a rational number.so,it can be expressed in the form of a/b.where a and b are positive co-prime integers and b≠0
      6+√2 = a/b
      √2 =a/b -6
      √2 = a- 6b/b
      so,√2 is a rational number
      But this contradicts the fact that √2 is an irrational number
      So,our assumption is wrong
      Therefore,6+√2 is an irrational number

    √3 is an irrational no.
    Let us assume that √3 is an ration no. And let √3=a/b where A and B are coprime no. And b is not =0
    √3= a/b
    Squaring both sides
    (√3)²= (a/b)²
    =b²3=a²/3
    a² is divisible by 3
    a is divisible by 3
    Now let us assume that a/b where a=3m
    √3=3m/b
    Squaring both sides (√3)²=(3m/b)²
    3=9m/b
    b²=3m²
    Sir what about after this I don't know what to do after this.

    • @lilkshmr

      After this
      b2=3m2
      3m=b2/3
      So b2 is divisible by 3
      Then b is also divisible by 3
      So these are not coprime no.
      So our assumption was wrong.
      So ✓3 is irrational no.

      Show that √5 is irrational.
      Proof. Let us assume √5 is a rational number.
      Then as per the definition of rational number √5 can be written in the form of p/q such that p and q are prime numbers and q is greater than 1.
      Therefore √5 =p/q.
      On squaring both the sides we get,
      5 = p2/q2
      ie .5xq = p2/q
      LHS : 5xq is an integer
      RHS :p2/q is a rational.
      LHS =/ RHS
      This is a contradiction to our assumption.
      Hence our assumption of √5 a rational number is false.
      Therefore √5 is irrational.

    Let us assume that √3 is rational number
    √3 = a/b ( where a and b are co-prime)
    Squaring both sides,
    (√3)² = (a/b)²
    3 = a²/b²
    3b² =a² ------1
    b²= a²/3
    a² is divisible by 3
    a is divisible by 3
    Now,
    a = 3m ( where a is the the value of any integer m )
    Putting value of a in equation 1
    3b² = (3m)²
    3b² = 9 m²
    b² = 9 m²/3
    b² = 3m²
    b² / 3 = m²
    b² is divisible by 3
    b is divisible by 3
    So a and b have 3 as common factor
    But a and b are co - prime
    This contradiction has arised due to our wrong assumption .
    Therefore √ 3 is irrational.

    Prove that Root5 is a irrational number
    Let us assum that root5 is a rational number
    Now root5 is in from of a/b , a&b is a integers , b is not equal to 0 , a&b is a co-prime
    Squaring both sides
    Root5 = a/b
    (Root5)² = (a/b)²
    5 = a²/b²
    5b² = a²
    a² = 5b²
    a² is divisible by 5
    So a is also divisible by 5
    a = 5c
    a² = 25c²
    5b² = 25c²
    b² = 5c²
    b² is divisible by 5
    So b is also divisible by 5
    5 is divisible by both a & b
    So a & b is irrational number
    Hence, Proved Root5 is a irrational

    Let us assume that root 3 is a rational number , then root 3 can be represented as root 3 = a÷b, where a and b are co-prime numbers and where b is not equal to 0
    So,
    Root 3 = a÷b
    (Root 3)^2 = a^2÷b^2 (squaring both side)
    Now,
    3=a^2÷b^2
    3=a^2÷b^2
    b^2=a^2÷3----equation 1
    So,by equation 1
    a^2 is divisible by 3
    also,a is also divisible by 3----(by th.-if p is a prime no.and if p is divisible by a^2 then p is also divisible by a where a is a positive integer)-----eqaution 2
    Now,
    Let a=3m,where m is +ve integer
    A/t/q
    (root 3)^2=(3m)^2÷b^2
    b^2=3m^2
    b^2÷3=m^2
    b^2 is divisible by 3
    then,b is also divisible by 3--- (by equation 1)
    So,our assumption is wrong that root 3 is rational, hence root 3 is irrational------ ( because we have assumed at the starting of the question that a and b are co-prime no. Which means a and b is only divisible by 1
    But at the end of the question a and b are both divisible by 3 other than 1 that is why it is not rational but irrational number)
    Hope you all like my way of writing the answer.....😉
