Answer 1

$3 \sqrt{18}-0.5 \sqrt{8}+ \sqrt{50} \\9 \sqrt{2}-0.5*2 \sqrt{2}+5 \sqrt{2} \\9 \sqrt{2}- \sqrt{2}+5 \sqrt{2} \\13 \sqrt{2} .$

Answer 2

$3* \sqrt{9*2} -0.5 \sqrt{4*2} + \sqrt{25*2} =3*3 \sqrt{2} -0.5*2 \sqrt{2} +5 \sqrt{2} = \\ \\ =9 \sqrt{2} - \sqrt{2} +5 \sqrt{2} =13 \sqrt{2} \\ \\ otvet: 13 \sqrt{2}$
