Answer 1

Объяснение:

$2\sqrt{18x}-\sqrt{98x}+\sqrt{32x} =2\sqrt{2*9x}-\sqrt{2*49x}+\sqrt{2*16x} =\\ = 6\sqrt{2x}-7\sqrt{2x}+4\sqrt{2x} =3\sqrt{2x} .\\\\\sqrt{36x} -3\sqrt{25x} +\sqrt{121x} =6\sqrt{x} -15\sqrt{x} +11\sqrt{x} =2\sqrt{x} .\\\\0,2\sqrt{75x} +\sqrt{300x} -5\sqrt{3x}=0,2\sqrt{25*3x}+\sqrt{100*3x}-5\sqrt{3x}=\\ =\sqrt{3x} +10\sqrt{3x}-5\sqrt{3x} =6\sqrt{3x}.\\\\ 7\sqrt{5x} +\sqrt{125x} -0,5\sqrt{80x} =7\sqrt{5x}+\sqrt{25*5x} -0,5\sqrt{16*5x}=\\ =7\sqrt{5x} +5\sqrt{5x} -2\sqrt{5x}=10\sqrt{5x}.$
