Answer 2

Explicação passo-a-passo:

$a)$

$\sqrt{ \dfrac{4}{25} }$

$\sqrt{ \dfrac{2 {}^{2} }{5 {}^{2} } }$

$\dfrac{2}{5}$

$b)$

$\sqrt{ \dfrac{16}{25} }$

$\sqrt{ \dfrac{4 {}^{2} }{5 {}^{2} } }$

$\dfrac{4}{5}$

$c)$

$\sqrt{ \dfrac{100}{25} }$

$\sqrt{ \dfrac{10 {}^{2} }{5 {}^{2} } }$

$\dfrac{10}{5}$

$2$

$d)$

$\sqrt{ \dfrac{144}{9} }$

$\sqrt{ \dfrac{12 {}^{2} }{3 {}^{2} } }$

$\dfrac{12}{3}$

$4$

$e)$

$\sqrt{ \dfrac{4}{100} }$

$\sqrt{ \dfrac{2 {}^{2} }{10 {}^{2} } }$

$\dfrac{2}{10}$

$\dfrac{2 {}^{ \div 2} }{10 {}^{ \div 2} }$

$\dfrac{1}{5}$
