    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

      @MalikOooo now see this method taught in my school-
      Q.prove that 6+√2 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

    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.

    इतनी उंचाई न देना प्रभु की धरती पराई लगने लगे,

    नहीं चाहिए ऐसी शक्ति जिसका निर्बल पर प्रयोग करू,
    नहीं चाहिए ऐसा भाव की किसीको देख जल-जल मरू,
    एसा ज्ञान मुझे न देना अभिमान जिसका होने लगे,
    एसी चतुराई भी न देना की लोगो को छलने लगे !!

    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.

    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.....😉
