I assume you want to rationalize the denominator You start with (1√2)/ (2√3) just multiply top and bottom by the conjugate of 2√3, which is 2√3 Now you have (1√2) (2√3) / (2√3) (2√3) = (1*2 2√2 1*√3 √6)/ (2^2 √3^2) = (2 2√2 √3 √6)/ (43) = 2 2√2 √3 √6 What you rationalize is the denominator of the fraction Eg 1/√2 is multiplied and divided by √2 to give √2/2 which is still irrational So you might be wondering what's the purpose of rationalising Let's do this, what is the value obtained if we add √2 √3 to 1/(√3 √2) It might be hard to tell right nowRD Sharma Solutions for Class 9 Maths Chapter 3 – Free PDF Download In Class 9, Rationalisation is one of the most important chapters RD Sharma Solutions for Class 9 Chapter 3 is about different algebraic identities and rationalisation of the denominatorA rationalisation is a process by which radicals in the denominator of a fraction are eliminated

How To Rationalize The Denominator 14 Steps With Pictures
Example 3 – Simplify a) 3√40 √ b) 2√3−54 c) What if there are variables in the expression?So √7 = a/b > (1) Square on both sides, we will have 7=a^2/b^2 => 7*b^2=a^2 > (2) From this we can conclude that a^2 is divisible by 7 and thus a is also divisible by 7 So we can write a as a product of 7 and another natural number, say c => a =7* c Substitute the value of a in equation 2If √2=1414√3=1732√5=2236 and √6=2449 find the value of If √2= 1414,√3 =1732,√5=2236 and √6= 2449, find the value of 2√3 2−√3 2−√3 2√3 √3−1 √31 A

You can solve it by rationalising the denominator, it means to make the denominator a rational number It is as follows Multiply both the denominator and numerator by 2√3 =Let x= √2√3 Then we can write (√2√2√3)= √2x Also (√2√2√3) = √2(√2√3) = √2x So (√2√2√3) (√2√2√3)= (√2x)(√2x)Given that `x= (sqrt3 sqrt2) /(sqrt3 sqrt2)` and `y = (sqrt3 sqrt2) /(sqrt3 sqrt2)` We need to find `x^2 xy y^2` Now we will rationalize xWe know that rationalization factor for `sqrt3sqrt2` is `sqrt3sqrt2` `sqrt3sqrt2`We will multiply numerator and denominator of the given expression `x= (sqrt3 sqrt2) /(sqrt3 sqrt2)` by `sqrt3 sqrt2`, to get
