Find the value of a and b if if 13+) = a +6313-1

Answer»

First 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
