Помогите, пожалуйста, с корнями!!!

Answer 1

$cfrac{4}{3} sqrt{6 cfrac{3}{4} } sqrt{cfrac{3}{4}} = cfrac{4}{3} sqrt{ cfrac{27}{4}*cfrac{3}{4} }= cfrac{4}{3} sqrt{ cfrac{81}{16} }=cfrac{4}{3}*cfrac{9}{4} =3 \ \ \ cfrac{15}{7} sqrt{ cfrac{14}{25} } sqrt{14} =cfrac{15}{7} sqrt{ cfrac{14*14}{25} } =cfrac{15}{7} *cfrac{14}{5}=3*2=6$
