Ответ:

  1. \(\dfrac{\sqrt{48}}{\sqrt{12}}=\sqrt{\dfrac{48}{12}}=\sqrt4=2\).

  2. \(\dfrac{\sqrt{63}}{\sqrt7}=\sqrt{\dfrac{63}{7}}=\sqrt9=3\).

  3. \(\sqrt{\dfrac{121}{169}}=\dfrac{\sqrt{121}}{\sqrt{169}}=\dfrac{11}{13}\).

  4. \(\sqrt{\dfrac{64}{0{,}25}}=\sqrt{256}=16\).

  5. \(\sqrt{\dfrac{225}{0{,}0025}}=\sqrt{90\,000}=30\sqrt{100}=300\).

  6. \(\sqrt{\dfrac{10^2}{0{,}0001}}=\sqrt{\dfrac{100}{0{,}0001}}=\sqrt{1\,000\,000}=1000\).

Ответ: 4) 2; 5) 3; 9) \(\dfrac{11}{13}\); 10) 16; 14) 300; 15) 1000.
