Ответ:
Используем свойства: \(\sqrt{a}\cdot\sqrt{b}=\sqrt{ab}\), \(\dfrac{\sqrt a}{\sqrt b}=\sqrt{\dfrac ab}\), \((\sqrt a)^2=a\).
- \(\sqrt{196}=14\).
- \(\sqrt{0.04}=0.2\).
- \(\sqrt2\cdot\sqrt8=\sqrt{16}=4\).
- \(\sqrt{10}\cdot\sqrt{10}=10\).
- \(\dfrac{\sqrt{300}}{\sqrt3}=\sqrt{100}=10\).
- \(\dfrac{\sqrt{48}}{\sqrt3}=\sqrt{16}=4\).
- \((\sqrt7)^2=7\).
- \((6\sqrt3)^2=6^2\cdot(\sqrt3)^2=36\cdot3=108\).
- \(\sqrt{2\dfrac79}=\sqrt{\dfrac{25}{9}}=\dfrac53\).
- \(\sqrt{0.36\cdot81}=\sqrt{29.16}=5.4\).
Ответ: 14; 0,2; 4; 10; 10; 4; 7; 108; \(\dfrac53\); 5,4.
