Задание номер 3 - сократиь дробь

Answer 1

$1. \frac{3- \sqrt{3} }{2 \sqrt{3} }= \frac{3- \sqrt{3}* \sqrt{3} }{2 \sqrt{3}* \sqrt{3} }= \frac{3-3}{2*3} = \frac{0}{6}=0$
$2. \frac{4b-2}{2 \sqrt{b}- \sqrt{2} } = \frac{4b-2*( \sqrt{4b} + \sqrt{2}) }{ (\sqrt{4b}- \sqrt{2})* (\sqrt{4b}+ \sqrt{2}) } = \frac{4b-2*( \sqrt{4b}+ \sqrt{2} )}{4b-2}= \sqrt{4b}+ \sqrt{2}$
