Question

задание номер 3 - сократиь дробь

Answer 1

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