racionalize as fracoes
​

Answer 1

$\frac{15}{ \sqrt{71} } = \frac{15}{ \sqrt{71} } \: . \: \frac{ \sqrt{71} }{ \sqrt{71} } = \frac{15 \sqrt{71} }{ \sqrt{71} \sqrt{71} } = \boxed{\boxed{\boxed{ \frac{15 \sqrt{71} }{71} }}} \\ \frac{3}{ \sqrt{62} } = \frac{3}{ \sqrt{62} } \: . \: \frac{ \sqrt{62} }{ \sqrt{62} } = \frac{3 \sqrt{62} }{ \sqrt{62} \sqrt{62} } = \boxed{\boxed{\boxed{ \frac{3 \sqrt{62} }{62} }}}$

Answer 2

Explicação passo-a-passo:

$\frac{15}{ \sqrt{71} } = \frac{15. \sqrt{71} }{( \sqrt{71}) {}^{2} } = \frac{15. \sqrt{71} }{71}$

$\frac{3}{ \sqrt{62} } = \frac{3 \sqrt{62} }{( \sqrt{62}) {}^{2} } = \frac{3 \sqrt{62} }{62}$
