Answer 2

$1)\sqrt{28}=\sqrt{4*7}=2\sqrt{7}$

$2)0,2\sqrt{75}=0,2\sqrt{25*3}=0,2*5\sqrt{3}=\sqrt{3}$

$3)\sqrt{27}=\sqrt{9*3}=3\sqrt{3}$

$4)\frac{1}{5} \sqrt{50}=0,2\sqrt{25*2}=0,2*5*\sqrt{2}=\sqrt{2}$

$5)\sqrt{72}=\sqrt{36*2}=6\sqrt{2}$

$6)0,01\sqrt{800}=0,01\sqrt{400*2}=0,01*20*\sqrt{2}=0,2\sqrt{2}$

$7)\sqrt{98}=\sqrt{49*2}=7\sqrt{2}$

$8)0,02\sqrt{1200}=0,02\sqrt{400*3}=0,02*20*\sqrt{3}=0,4\sqrt{3}$

$9)\sqrt{112}=\sqrt{16*7}=4\sqrt{7}$

$10)-0,125\sqrt{320}=-0,125\sqrt{64*5}=-0,125*8*\sqrt{5}=-\sqrt{5}$

$11)\sqrt{126}=\sqrt{9*14}=3\sqrt{14}$

$12)-0,25\sqrt{512}=-0,25\sqrt{256*2}=-0,25*16*\sqrt{2}=-4\sqrt{2}$
