Question

Rationalizeaza numitorul:
$\frac{3}{2 \sqrt{7} } \\ \frac{11}{3 \sqrt{2} }$
la astea nu prea ma pricep:))​

Answer 1

Răspuns:

$\frac{3}{2 \sqrt{7} } = \frac{3}{2 \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} } = \frac{3 \sqrt{7} }{2 \sqrt{7} \sqrt{7} } = \frac{3 \sqrt{7} }{14}$

$\frac{11}{3 \sqrt{2} } = \frac{11}{3 \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{11 \sqrt{2} }{3 \sqrt{2} \sqrt{2} } = \frac{11 \sqrt{2} }{6}$
