Step-by-step explanation:

GIVEN \frac{ \sqrt{3} + 1 }{ \sqrt{3}  - 1}  = a + b \sqrt{3}  \\

TO FIND

Value of a and b

SOLUTION

 \frac{ \sqrt{3} + 1 }{ \sqrt{3}  - 1}  = a + b \sqrt{3}  \\  \\  =   \frac{( \sqrt{3} + 1) }{ (\sqrt{3}  - 1)}  \times   \frac{ (\sqrt{3}  + 1)}{ (\sqrt{3 } + 1) }  \\  \\  =  \frac{ {( \sqrt{3}  + 1)}^{2} }{ { \sqrt{3} }^{2}  -  {1}^{2} }  \\  \\  =   \frac{ { \sqrt{3} }^{2}  +  {1}^{2} + 2 \times  \sqrt{3 }\times {1}  }{ 3 - 1}  \\   \\  =  \frac{3 + 1 + 2 \sqrt{3} }{2}  =  \frac{4 + 2 \sqrt{3} }{2} \\  \\  =  \frac{2(2 +  \sqrt{3}) }{2}   = 2 +  \sqrt{3}  \\ \\  hence \: a  = 2 \:  \: and \:  \: b = 1
