Answer:

a = 7 or b= 4

Step-by-step explanation:

 \frac{2 +  \sqrt{3} }{2 -  \sqrt{3} }  = a + b \sqrt{3}  \\ at \: rationalise \\  \frac{2 +  \sqrt{3} }{2 -  \sqrt{3} }  \times  \frac{2 +  \sqrt{3} }{2 +  \sqrt{3} }  \\  \frac{4 + 3 + 4 \sqrt{3} }{4 - 3}  \\ 7 + 4 \sqrt{3}  = a + b \sqrt{3}  \\

here a = 7 , or b =4

i hope its helpfull.
