Question

The conjugate surd of 2+√3 is ………… *​

Answer 1

If a = √3 and b= 1 ,then denominator is ( a-b) , if we multiply ( a+b) or √3+1 , it will a2-b2 and √3 will be squared off.

= 2(\sqrt{3}+1) .In above example √3+1 is used as rationalizing factor which is a conjugate to √3-1 .

Answer 2

The conjugate surd of 2 + √3 is 2 - √3

Given :

The surd 2 + √3

To find :

The conjugate surd of 2 + √3

Solution :

Step 1 of 2 :

Write down the given surd

The given surd is 2 + √3

Step 2 of 2 :

Find the conjugate surd of 2 + √3

We know that for any given surd is a + √b the conjugate surd of a + √b is a - √b

Thus conjugate surd of 2 + √3

= 2 - √3
