Question

pelo amor de Deus mi ajudem a responder este treco

Answer 1

$e) \\ \\ \sqrt{ \dfrac{36}{225}} \\ \\ \\ \dfrac{ \sqrt{36}}{ \sqrt{225}} \\ \\ \\ \dfrac{6}{15} \\ \\ \\ => \dfrac{2}{5}$

=============

$f) \\ \\ \sqrt{1 \dfrac{7}{9} } \\ \\ \\ \sqrt{ \dfrac{1 *7}{9} } \\ \\ \\ \sqrt{ \dfrac{7}{9}} \\ \\ \\ \dfrac{ \sqrt{7}}{ \sqrt{9}} \\ \\ \\ => \dfrac{ \sqrt{7}}{3}$

=============

$g) \\ \\ \sqrt{1- \dfrac{5}{9}}$

mmc = 9

$\sqrt{ \dfrac{9 - 5}{9}} \\ \\ \\ \sqrt{ \dfrac{4}{9}} \\ \\ \\ \dfrac{ \sqrt{4}}{ \sqrt{9}} \\ \\ \\ => \dfrac{2}{3}$

===============

$h) \\ \\ \sqrt{2- \dfrac{14}{25}}$

mmc = 25

$\sqrt{\dfrac{50 - 14}{25}} \\ \\ \\ \sqrt{\dfrac{36}{25}} \\ \\ \\ \dfrac{ \sqrt{36}}{ \sqrt{25}} \\ \\ \\ => \dfrac{6}{5}$
