Find the value of a and b if (3√2)/(3√2)=ab√2class 9th Mathematics important question.

√ 3 ∈ Q(√ 2), ie there exist a,b ∈ Qsuch that √ 3 = a b √ 2 Then (ab √ 2)2 = (a22b2)2ab √ 2, so one gets 3−a2−2b2 = 2ab √ 2 Since √ 2 ∈ Q the only possibility is that 2ab = 0, which implies that either a = 0 or b = 0 If a = 0 then one gets √ 3 = b √ 2, ie √ √ 6 = 2b ∈ Q, which is a contradiction If b = 0 then one gets 3 = a ∈ Q, which is again a contradiction Therefore √ 3 ∈. √ 2 = ab √ 2 a,b ∈ Z ⊆ R Prove Z√ 2 is a subring of R Proof Consider a b √ 2,c d √ 2 ∈ Z√ 2 where a,b,c,d ∈ Z Then (a b √ 2) (c d √ 2) = (a c) (b d) √ 2 ∈ Z√ 2, so Z√ 2 is closed under addition Also, (a b √ 2)(c d √ 2) = (ac2bd)(adbc) √ 2 ∈ Z√ 2sinceac2bd,adbc. According to the property of square root we have a√bc√b= (ac)√b if we apply this property on 2√3√3 we will get ( 21)√3=3√3 Perhaps the simplest way of thinking about this is to answer.

Solution Now, x= √3√2 √3−√2 × √3√2 √3√2 , Multiplying numerator and denominator by √3√2 = (√3√2)2 (√3)2−(√2)2 Using identity, (ab)(a−b)=a2−b2 = (√3)2(√2)22√3 √2 3−2 Using identity, (ab)2 =a2b22ab = 322√6 1 =322√6 ∴x=52√6 −(i) On squaring both sides, we get, x2 =(52√6)2.

Answer (1 of 3) We take (2√3) = a equation (2√3) = b equation In a equation we take 2 and Multiply by equation b * (2)×(2√3) Then we multiply 2 by 2 and then 2 by √3 “ in above equation” * 2×2 = 4 * 2×√3 = 2√3 Then we add the above equation ( solvi. In Mathematics, surds are the values in square root that cannot be further simplified into whole numbers or integers Surds are irrational numbers The examples of surds are √2, √3, √5, etc, as these values cannot be further simplified If we further simply them, we get decimal values, such as √2 = √3 =.  The decimal expansion of the number √2 is (a) a finite decimal (b) (c) nonterminating recurring asked in Mathematics by RahulSingh (.

 The rationalisation factor of √3 is A √3 B 1/√3 C 2√3 D 2√3 asked 2 hours ago in Number System by Madhuwant ( 1k points) rationalisation.  🔴 Answer 1 🔴 on a question A √2√3√2√3 = with explanation pls the answers to answerhelpercom. Originally Answered If ab=√3 and ab=√2, then what is 8ab (a²b²)?.

A b = √3 Hence, ( a b )^2 = 3 So, a^2 2ab b^2 = 3 Similarly, a^2 2ab b^2 = 2 Now, subtracting both the above equations, we get, 4ab = 1 So, the value of a×b is 1/4. 3 √ (c) Show that the result in part (a) could have been obtained by writing (−1 3i)3/2 = (−1 √ 3i)31/2 and first cubing −1 √ 3i Solution (a)(−1 √ 3i)3/2 = e32 log(−1 √ 3i) = e3 2 (ln2i( 2π 3 2πn)) = 2 √ 2eiπ(3n1), n ∈ Z, which is 2. 12 is 4 times 3 √12 = √ (4 × 3) Use the rule √ (4 × 3) = √4 × √3 And the square root of 4 is 2 √4 × √3 = 2√3 So √12 is simpler as 2√3 Another example.

 Answer a Explanation √23 = Since the decimal expansion of the number is nonterminating nonrecurring Hence, it is an irrational number MCQ PART2 Question 1 The value of 22−−√3− −−−√4 is equal to (a) 2–16 (b) 26. Given that x=32√3 we need to find √x1/√x Therefore we have(√x1/√x)^2= x1/x 2 using (ab)^2=a^2b^22ab Substituting the value of x=(32√3)1/(32√3)2 Now, rationalize 1/x=(96√332√36)/3 =(128√3)/3 =4(32√3)/3 (√x1/√x)=±(√(4(32√3)/3) =±(2√(32√3)/3).
