Answer 1

Răspuns:

$\frac{8 \sqrt{3} }{6 \sqrt{2} } = \frac{ \sqrt{2} \times 8 \sqrt{3} }{ \sqrt{2} \times 6 \sqrt{2} } = \frac{8 \sqrt{6} }{12} = \frac{2 \sqrt{6} }{3}$

$\frac{21}{ \sqrt{147} } = \frac{21 \sqrt{147} }{ \sqrt{147} \times \sqrt{147} } = \frac{21 \sqrt{147} }{147} = \frac{ \sqrt{147} }{7}$
