Answer 1

Explicação passo-a-passo:

.

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

$\dfrac{10}{ \sqrt{5} } \times \dfrac{ \sqrt{5} }{ \sqrt{5} }$

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

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

$2 \sqrt{5}$

.

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

$\dfrac{2 \sqrt{2} }{ \sqrt{3} } \times \dfrac{ \sqrt{3} }{ \sqrt{3} }$

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

$\dfrac{2 \sqrt{6} }{3}$

.

$\dfrac{9}{2 \sqrt{3} }$

$\dfrac{9}{2 \sqrt{3} } \times \dfrac{ \sqrt{3} }{ \sqrt{3} }$

$\dfrac{9 \sqrt{3} }{2 \sqrt{3} \sqrt{3} }$

$\dfrac{9 \sqrt{3} }{2 \times 3}$

$\dfrac{9 \sqrt{3} }{6}$

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