Solution:- Euclid's division lemma : Let a and b be any two positive Integers . Then there exist two unique whole numbers q and r such that a=bq+r , 0≤r<b Now , start with a larger integer , that is 337554, Apply the division lemma to 337554 and 26676, 337554=26676×12+17442 26676=17442×1+9234 17442=9234×1+8208 9234=8208×1+1026 8208=1026×8+0 The remainder has now become zero , so our procedure stops. Since the divisor at this stage is 1026 . ∴HCF(337554,26676)=1026

Let √5 a rational number Where √5=a/b and a and b are co primes and b not equal to 0 Square them 5=a square / b square Cross multiply 5b square is equal to a square B is a factor of a B is also a factor of a square Now take A is equal to 5 c Square them A square is equal to 25 c square We know that a square is equal to 5 b square So now 5 b square is equal to 25 c square Simplify them We get b square is equal to 5 c square Now 5 is a factor of b square and b It contradict to our assumption that a and b are co primes Hence our assumption is wrong Therefore √5 is an irrational number Hence proved

Let √5 =a/b (where a/b is an rational number where a/b are co-primes) Squaring both the sides 5 = a2/b2 5b2 = a2 ---1 Thus 5 divides a2 , 5 divides a Now take any other integer as c such that a=5c squaring both the sides a2=25c2 --- 2 put a value from eq-1 into eq-2 5 b2 =25 c 2 b2=5c2 5 divides b2 and 5 divide b We let a&b are co-primes but here we are getting 5 as a factor of both a &b. So our prediction that a&b are co-primes is wrong Thus ✓5 is an Irrational number.

(17 × 11 × 2 + 17 × 11 × 5 ) = 17 × 11 ( 2 + 5 ) {explanation : taking 17 and 11 as common } = 187 ( 2 + 5 ) here 187 is a factor of (17 × 11 × 2 + 17 × 11 × 5 ) so we can say that (17 × 11 × 2 + 17 × 11 × 5 ) is composite number because it has factor other than 1

Prove that √2 is irrational

Prove that root 2 is an irrational number. Rational numbers are integers that are expressed in the form of p / q where p and q are both co-prime numbers and q is non-zero. Answer: Hence proved that √2 is an irrational number. Let's find if √2 is irrational. Explanation: To prove that √2 is an irrational number, we will use the contradiction method. Let us assume that √2 is a rational number with p and q as co-prime integers and q ≠ 0 ⇒ √2 = p/q On squaring both sides we get, ⇒ 2q2 = p2 ⇒ Here, 2q2 is a multiple of 2 and hence it is even. Thus, p2 is an even number. Therefore, p is also even. So we can assume that p = 2x where x is an integer. By substituting this value of p in 2q2 = p2, we get ⇒ 2q2 = (2x)2 ⇒ 2q2 = 4x2 ⇒ q2 = 2x2 ⇒ q2 is an even number. Therefore, q is also even. Since p and q both are even numbers, they have 2 as a common multiple which means that p and q are not co-prime numbers as their HCF is 2. This leads to the contradiction that root 2 is a rational number in the form of p/q with "p and q both co-prime numbers" and q ≠ 0. Thus, √2 is an irrational number by the contradiction method.
