Ответ:
- \(\sqrt9=3\).
- \(\sqrt{100}=10\).
- \(\sqrt{289}=17\).
- \(\sqrt{6400}=80\).
- \(\sqrt{45}=3\sqrt5\).
- \(\sqrt{32}=4\sqrt2\).
- \(\sqrt{0.36}=0.6\).
- \(\sqrt7\cdot\sqrt7=7\).
- \(\sqrt{50}\cdot\sqrt2=\sqrt{100}=10\).
- \(\sqrt{1.6}=\sqrt{16/10}=2\sqrt{10}/5\).
- \((\sqrt6)^2=6\).
- \((2\sqrt{11})^2=4\cdot11=44\).
- \(\sqrt{2250}=15\sqrt{10}\).
- \(\sqrt{64+16}=\sqrt{80}=4\sqrt5\).
- \(\sqrt{64\cdot16}=\sqrt{1024}=32\).
- \(\sqrt{17^2-8^2}=\sqrt{289-64}=\sqrt{225}=15\).
- \((\sqrt6)^3=6\sqrt6\).
- \(3/\sqrt3=\sqrt3\).
- По формуле разности квадратов: \((3-\sqrt2)(3+\sqrt2)=9-2=7\).
- \((\sqrt3+2)^2=3+4\sqrt3+4=7+4\sqrt3\).
