Answer 2

$1) \\(3\sqrt{18} +9\sqrt{18} ):2\sqrt{2} +3\sqrt{64} =\\\sqrt{18} = 3\sqrt{2} \\\sqrt{64} = 8 => 36\sqrt{2}:2\sqrt{2} +24=18+24=42\\2)\\(4\sqrt{12} +6\sqrt{12} ):5\sqrt{3} +4\sqrt{16}=\\\sqrt{12} =2\sqrt{3} \\\sqrt{16} =4 => 20\sqrt{3} :5\sqrt{3} +16=4+16=20$$3)\\(4\sqrt{25} +6\sqrt{16} ):\sqrt{4}+3\sqrt{36} =\\\sqrt{25} =5\\\sqrt{36} =6 => 44:\sqrt{4} +18= \frac{44}{\sqrt{4}} +18=\frac{44\sqrt{4} }{4} +18=11\sqrt{4} +18\\4)\\(-4\sqrt{49} -2\sqrt{4}):2+3\sqrt{81} =\\\sqrt{49} =7\\\sqrt{4} =2\\\sqrt{81} =9 => (-14-4):2+27=-18:2+27=-9+27=18$
