Answer 1

Ответ:

$1) \sqrt{360*490} = 60*70 = 420\\\\2)\sqrt{32*72} = \sqrt{2304}= 48\\\\3) \sqrt{125*80} =\sqrt{10000} = 100 \\\\4)\sqrt{3,6*810} = \sqrt{2916} = 54\\\\5)\sqrt{275*625} =\sqrt{5^{2} *11*5^{4} } = 125\sqrt{11} \\\\6) \sqrt{331*776} = \sqrt{2^2*5^2*3.31*2^2*194} = 20\sqrt{642.14} \\\\7)\sqrt{45*80*0.16} = \sqrt{3^2*5*4^2*0.4^2} = 4.8\sqrt{5} \\\\8)\sqrt{98*24*27} = \sqrt{7^{2}*2*2^2*6 *3^2*3} = 42\sqrt{36}$
