$sf frac{4}{2 + sqrt{3} }$

$sf = frac{4}{2 + sqrt{3} } times frac{2 - sqrt{3} }{2 - sqrt{3} }$

$sf = frac{4 ( 2 - sqrt{3} )}{(2 + sqrt{3} )( 2 - sqrt{3}) }$

$sf = frac{4 ( 2 - sqrt{3} )}{4 - 3}$

$sf = frac{4 (2 - sqrt{3}) }{1}$

$sf = 4( 2 - sqrt{3} )$

$sf = 4 times 2 - 4 sqrt{3}$

$sf = 8 - 4 sqrt{3}$
