Решите задачу:

$1)\; \; \sqrt{0,0064}=0,08\; \; \; verno\\\\2)\; \; (\sqrt{14})^2-\sqrt{1,21}+\sqrt{\dfrac{16}{25}}=14-1,1+\dfrac{4}{5}=12,9+0,8=13,7\\\\3)\; \; 5\, \sqrt{0,16}-\dfrac{3}{8}\cdot \sqrt{\dfrac{16}{9}}-\dfrac{4}{9}\cdot \sqrt{\dfrac{81}{256}}=5\cdot 0,4-\dfrac{3}{8}\cdot \dfrac{4}{3}-\dfrac{4}{9}\cdot \dfrac{9}{16}=\\\\=2-0,5-0,25=1,25$

$4)\; \; \sqrt{(-0,09)^2}+\dfrac{10}{13}\cdot \sqrt{27,04}+\Big(-\dfrac{1}{3}\, \sqrt{27}\Big)^2= 0,09+\dfrac{10}{13}\cdot \sqrt{\dfrac{676}{25}}+\dfrac{1}{9}\cdot 27=\\\\=0,09+\dfrac{10}{13}\cdot \dfrac{26}{5}+3=0,09+4+3=7,09\\\\5)\; \; 0,49\cdot \sqrt\frac{225}{49}}-\sqrt{26^2-24^2}=0,49\cdot \dfrac{15}{7}-\sqrt{(26-24)(26+24)}=\\\\=\dfrac{49\cdot 15}{100\cdot 7}-\sqrt{2\cdot 50}=\dfrac{7\cdot 15}{100}-\sqrt{100}=1,05-10=-8,95$

$6)\; \; \sqrt{(\sqrt{50}-1)(\sqrt{50}+1)}=\sqrt{50-1}=\sqrt{49}=7\\\\7)\; \; \Big(\sqrt{17}-3\Big)^2+6\sqrt{17}=17+9-6\sqrt{17}+6\sqrt{17}=26\\\\8)\; \; \sqrt{(5-\sqrt{34})^2}-\sqrt{34}=|5-\sqrt{34}|-\sqrt{34}=(\sqrt{34}-5)-\sqrt{34}=-5\\\\9)\; \; \sqrt{(-3)^6\cdot (-0,2)^2\cdot (-7)^4} -64,6=\sqrt{((-3)^3)^2\, \cdot \, (-0,2)^2\, \cdot \, (49)^2}-64,6=\\\\=\Big(|(-3)^3|\cdot |-0,2|\cdot 49\Big)-64,6=\Big(|-27|\cdot 0,2\cdot 49\Big)-64,6=\\\\=\Big(27\cdot 0,2\cdot 49\Big)-64,6=264,6-64,6=200$
