Racionalizar essas frações
$.$

Answer 1

a)
$\frac{4}{ \sqrt{36} } = \frac{4}{6} = \frac{2}{3}$
c)
$\frac{5}{ \sqrt{8} } = \frac{5}{ \sqrt{8} } \times \frac{ \sqrt{8} }{ \sqrt{8} } = \frac{5 \sqrt{8} }{8}$
d)
$\frac{11}{ \sqrt{12} } = \frac{11}{ \sqrt{12} } \times \frac{ \sqrt{12} }{ \sqrt{12} } = \frac{11 \sqrt{12} }{12}$
e)
$\frac{35}{ \sqrt{122} } = \frac{35}{ \sqrt{122} } \times \frac{ \sqrt{122} }{ \sqrt{122} } = \frac{35 \sqrt{122} }{122}$
f)
$\frac{4}{ \sqrt{10} } = \frac{4}{ \sqrt{10} } \times \frac{ \sqrt{10} }{ \sqrt{10} } = \frac{4 \sqrt{10} }{10} = \frac{2 \sqrt{10} }{5}$
