Ответ:
- \(\frac18\cdot0.8\cdot10=1\).
- \(\sqrt{49}-\sqrt{2\sqrt{64}}-1=7-\sqrt{16}-1=7-4-1=2\).
- \(2\sqrt9-\sqrt{\sqrt{36}}+3=2\cdot3-\sqrt6+3=9-\sqrt6\).
- \(10\sqrt{0.5^2-0.3^2}=10\sqrt{0.25-0.09}=10\sqrt{0.16}=10\cdot0.4=4\).
- \(6\cdot\left(\sqrt{\frac56}\right)^2=6\cdot\frac56=5\).
- \(\sqrt{4^2+20}=\sqrt{16+20}=\sqrt{36}=6\).
Ответ: 1) 1; 2) 2; 3) \(9-\sqrt6\); 4) 4; 5) 5; 6) 6.
