Odpowiedź:
[tex]\sqrt{20} *\sqrt{5} =\sqrt{20*5} =\sqrt{100} =10[/tex]
[tex]\sqrt{10 } *\sqrt{12,1} =\sqrt{10*12,1} =\sqrt{121} =11[/tex]
[tex]\sqrt{7} *\sqrt{28} =\sqrt{7*28} =\sqrt{196} =14[/tex]
[tex]\sqrt{2} *\sqrt{32} =\sqrt{2*32} =\sqrt{64} =8[/tex]
[tex]\sqrt{50} *\sqrt{\frac{1}{2} } =\sqrt{50*\frac{1}{2} } =\sqrt{25} =5[/tex]
[tex]\sqrt{8} *\sqrt{32} =\sqrt{8*32} =\sqrt{256} =16[/tex]
[tex]\sqrt{20} *\sqrt{10} *\sqrt{2} =\sqrt{20*10*2} =\sqrt{400} =20[/tex]
[tex]\sqrt{18} :\sqrt{2} =\sqrt{18:2} =\sqrt{9} =3[/tex]
[tex]\sqrt{56} :\sqrt{3,5} =\sqrt{56:3,5} =\sqrt{16} =4[/tex]
[tex]\sqrt{125}:\sqrt{5} =\sqrt{125:5} =\sqrt{25} =5[/tex]
[tex]\sqrt{0,03} :\sqrt{3} =\sqrt{\frac{3}{100} :3} =\sqrt{\frac{3}{100}*\frac{1}{3} } =\sqrt{\frac{1}{100} } =\frac{1}{10}[/tex]
