  1. \(\dfrac{\sqrt{48}}{\sqrt{3}}=\sqrt{\dfrac{48}{3}}=\sqrt{16}=4\).
  2. \(\dfrac{\sqrt{150}}{\sqrt{6}}=\sqrt{25}=5\).
  3. \(\dfrac{\sqrt{6.3}}{\sqrt{0.7}}=\sqrt{9}=3\).
  4. \(\dfrac{\sqrt{98}}{\sqrt{242}}=\sqrt{\dfrac{49}{121}}=\dfrac{7}{11}\).
  5. \(\dfrac{\sqrt{6}\cdot\sqrt{2}}{\sqrt{3}}=\sqrt{\dfrac{12}{3}}=2\).
