Answer 1

Răspuns:

$\sqrt{2\frac{7}{9} } =\sqrt{\frac{2*9+7}{9}} =\sqrt{\frac{25}{9} }=\frac{5}{3} \\\\\sqrt{5\frac{19}{25} } =\sqrt{\frac{5*25+19}{25} } =\sqrt{\frac{144}{25} } =12/5\\\\\sqrt{\frac{11*9+1}{9} } =\sqrt{\frac{100}{9} } =\frac{10}{3} \\\\\sqrt{\frac{7*16+9}{16} } =\sqrt{\frac{121}{16} } =\frac{11}{4}$$\sqrt{\frac{1*49+32}{49} } =\sqrt{\frac{81}{49} } =\frac{9}{7}$
