Question

rationalizati 10/3V5²,3/V75,8/V6 va rog mult dau corona V este radical / linia de fractie ​

Answer 1

Explicație pas cu pas:

$\frac{10}{3 \sqrt{5} } = \frac{10 \times \sqrt{5} }{3 \times \sqrt{5} \times \sqrt{5} } = \frac{10 \sqrt{5} }{3 \times 5} = \frac{2 \sqrt{5} }{3} \\ \frac{3}{ \sqrt{75} } = \frac{3}{5 \sqrt{3} } = \frac{3 \sqrt{3} }{5 \times \sqrt{3} \times \sqrt{3} } = \frac{3 \sqrt{3} }{5 \times 3} = \frac{ \sqrt{3} }{5} \\ \frac{8}{ \sqrt{6} } = \frac{8 \times \sqrt{6} }{ \sqrt{6} \times \sqrt{6} } = \frac{8 \sqrt{6} }{6} = \frac{4 \sqrt{6} }{3}$
