Question

vă rog frumos ajutatima la exercițiile 9 si 10

Answer 1

9.
$\sqrt{ \frac{12}{5} }$
$\sqrt{ \frac{14}{7} } = \sqrt{2}$
$\sqrt{ \frac{21}{3} } = \sqrt{7}$
$\sqrt{ \frac{11}{8} }$
$\sqrt{ \frac{40}{8} } = \sqrt{5}$

10.
$\frac{ \sqrt{3} }{ \sqrt{2} }$
$\frac{ \sqrt{13} }{ \sqrt{7} }$
$\frac{ \sqrt{13} }{ \sqrt{10} }$
$\frac{ \sqrt{21} }{ \sqrt{9} } = \frac{ \sqrt{21} }{3}$
$\frac{ \sqrt{471} }{ \sqrt{90} } = \frac{ \sqrt{471} }{3 \sqrt{10} }$
