Question

ME AJUDA POR FAVOR :/

Answer 1

Resposta:

Explicação passo a passo:

$a)$

$\frac{2}{\sqrt{3} }=\frac{2\sqrt{3} }{\sqrt{3}\:.\:\sqrt{3} } =\frac{2\sqrt{3} }{\sqrt{9} }=\frac{2\sqrt{3} }{3}$

$b)$

$\frac{3}{\sqrt{2} }=\frac{3\sqrt{2} }{\sqrt{2}\:.\:\sqrt{2} } =\frac{3\sqrt{2} }{\sqrt{4} }=\frac{3\sqrt{2} }{2}$

$c)$

$\frac{3}{4\sqrt{5} } =\frac{3\sqrt{5} }{4\sqrt{5}\:.\:\sqrt{5}}=\frac{3\sqrt{5} }{4\sqrt{25} } =\frac{3\sqrt{5} }{4\:.\:5} =\frac{3\sqrt{5} }{20}$

$d)$

$\frac{m}{\sqrt{n} } =\frac{m.\sqrt{n} }{\sqrt{n}\:.\:\sqrt{n} } =\frac{m\sqrt{n} }{\sqrt{n^{2} } } =\frac{m\sqrt{n} }{n}$
