Zgjidhja e ushtrimit 5

Dimë që: $\Big(\dfrac{\sqrt{a}}{\sqrt{b}}=\sqrt{\dfrac{a}{b}}$ si dhe $\sqrt[3]{\dfrac{a}{b}}=\dfrac{\sqrt[3]{a}}{\sqrt[3]{b}}\Big)$. $\sqrt{\dfrac{9}{25}}=\dfrac{\sqrt{9}}{\sqrt{25}}=\dfrac{3}{5}$. Gjeni sipas shembullit:

1. $\sqrt{\dfrac{16}{49}}$; $\sqrt{\dfrac{25}{81}}$; $\sqrt{\dfrac{4}{121}}$; $\sqrt{\dfrac{49}{81}}$; $\sqrt{0.16}$
2. $\sqrt[3]{\dfrac{8}{27}}$; $\sqrt[3]{\dfrac{1}{8}}$; $\sqrt[3]{\dfrac{64}{125}}$; $\sqrt[3]{\dfrac{1}{64}}$
