Answer:

$\frac{4 - 2 \sqrt{3} }{2} \\ = 2 - \sqrt{3}$

Step-by-step explanation:

FIRST MULTIPLY BOTH THE NUMERATOR AND DENOMIMATOR WITH THE CONJUGATE OF THE DENOMINATOR (√3-1)

THEREFORE

$\frac{( \sqrt{3} - 1)( \sqrt{3} - 1)}{( \sqrt{3} + 1)( \sqrt{3} - 1)}$

SIMPLIFYING WE GET AS

$\frac{4 - 2 \sqrt{3} }{2} \\ = 2 - \sqrt{3}$
