Question

racionalize o denominador das fraçoes

Answer 1

$\frac{5}{ \sqrt{14} } . \frac{ \sqrt{14} }{ \sqrt{14} } = \frac{5 \sqrt{14} }{14}$

$\frac{12}{ \sqrt{6} }. \frac{ \sqrt{6} }{ \sqrt{6} } = \frac{12 \sqrt{6} }{6}$ = 2√6

$\frac{3}{2 \sqrt{5} } . \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{3 \sqrt{5} }{2.5} = \frac{3 \sqrt{5}}{10}$
