Question

√3-1/√3+1=a+b√3 find a and b

Answer 1

in this q we have to find out the value of a and b 
you have to rationalize the denominator by multiplying both numerator and denominator with root 3-1

then you will get{ root 3 + 1 }2/{root 3}2- {1}2

that will be = 4+2*root3  /2

2{2+root 3 } / 2{1}

and finally you are left with 2+root3

therefore, a = 2 and b =1
