$\frac{1}{ \sqrt[3]{2} }$
$\frac{3}{ \sqrt[3]{3} }$
$\frac{ \sqrt{3} }{ \sqrt{2} }$
$\frac{ \sqrt{10} }{ 5\sqrt{2} }$

oliff96 $\frac{1}{\sqrt[3]{2}} = \frac{1}{\sqrt[3]{2}} * \frac{\sqrt[3]{2}}{\sqrt[3]{2}} = \frac{\sqrt[3]{2}}{8}$
$\frac{3}{\sqrt[3]{3}} = \frac{3}{\sqrt[3]{3}} * \frac{\sqrt[3]{3}}{\sqrt[3]{3}} = \frac{3\sqrt[3]{3}}{27} =\frac{\sqrt[3]{3}}{9}$
$\frac{\sqrt{3}}{\sqrt{2}} = \frac{\sqrt{3}}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}} = \frac{\sqrt{6}}{2}$
$\frac{\sqrt{10}}{5\sqrt{2}} = \frac{\sqrt{10}}{5\sqrt{2}} * \frac{5\sqrt{2}}{5\sqrt{2}} = \frac{5\sqrt{20}}{100} = \frac{\sqrt{20}}{20}$

1.Dokończ zdania! Dear Paul, I've just finished my exams and I'm really looking forward to the summer break.I've been thinking about going on an activity holiday. But I'm not sure if I should spend a week by the sea or go on a mountain trek. My cousin Ted said he'd join me.He's very keen on scuba diving and really wants to explore a coral reef! I'm not so brave. I would be frightened of the white sharks! My parents said they'd prefer we went on an organised tour somewhere. I don't like going on holiday alone. I personally think they're boring. We'd have to stick to a schedule all the time. Do you have any ideas about where we could go? Maybe you could even come along! Write soon.
