Question

Aah Me ajudemm pfv!!!

Answer 1

Explicação passo-a-passo:

$\frac{1}{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{5}{5}$

$\frac{7}{ \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} } = \frac{7 \sqrt{7} }{7} = \sqrt{7}$

$\frac{3}{ \sqrt{11} } \times \frac{ \sqrt{11} }{ \sqrt{11} } = \frac{3 \sqrt{11} }{11}$

$\frac{1}{ \sqrt{a} } \times \frac{ \sqrt{a} }{ \sqrt{a}} = \frac{ \sqrt{a} }{a}$

$\frac{p}{ \sqrt{p} } \times \frac{ \sqrt{p} }{ \sqrt{p} } = \frac{p \sqrt{p}}{p} = \sqrt{p}$

$\frac{10 }{3 \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{10 \sqrt{5} }{3 \times 5} = \frac{2 \sqrt{5} }{3}$
