помогите 2 вариант срочно ​

Answer 1

$1) \sqrt{16*36} =4*6=24$

$2) \sqrt{4*1.69} =2*1.3=2.6$

$3)\sqrt{0.01*169*900}=0.1*13*30=39$

$4) 4\sqrt{10}=\sqrt{10*4^{2} }=\sqrt{160}$

$5)\sqrt{121*37}=\sqrt{11^{2} *37} =11\sqrt{37}$

$6) \sqrt{16*42}+\sqrt{256*42}=4\sqrt{42}+16\sqrt{42} =20\sqrt{42}$

$7) \sqrt{63} =\sqrt{9*7} =3\sqrt{7}$

$8) -\sqrt{9c}-\sqrt{81c}-\sqrt{64c} =-3\sqrt{c} -9\sqrt{c}-8\sqrt{c}=-20\sqrt{c}$

$9)-6\sqrt{92} +\sqrt{23} =-6\sqrt{23*2^{2} } +\sqrt{23}=-12\sqrt{23} +\sqrt{23}=-11\sqrt{23}$

$10)\frac{\sqrt{144} }{\sqrt{9} } =\frac{12}{3} =-4$

$11) \frac{\sqrt{9} }{\sqrt{2}*\sqrt{72} } =\frac{3}{\sqrt{2*72} } =\frac{3}{\sqrt{144} } =\frac{3}{12} =\frac{1}{4}$
