Answer 1

$\frac{1}{10 * 0,008}+( \frac{4}{2 \sqrt{3}}-3 \sqrt{2})* \sqrt{6}+6 \sqrt{3}-2 \sqrt{2}=$

$=\frac{1}{0,08} +( \frac{2 \sqrt{3} }{3} -3 \sqrt{2})* \sqrt{6}+6 \sqrt{3}-2 \sqrt{2}=$

$= \frac{25}{2}+ \frac{2 *\sqrt{3}*\sqrt{6}}{3}-3* \sqrt{2}* \sqrt{6}+6 \sqrt{3}-2 \sqrt{2}=$

$= \frac{25}{2}+ \frac{2*3* \sqrt{2} }{3}-3*2* \sqrt{3} + 6 \sqrt{3} -2 \sqrt{2} =$

$= \frac{25}{2}+ 2 \sqrt{2} -6 \sqrt{3} +6 \sqrt{3}-2 \sqrt{2}= \frac{25}{2}=12,5$
