c)[tex]\frac{\sqrt{52}*\sqrt{363} }{\sqrt{30}*\sqrt{130} } =\frac{2\sqrt{13}*11\sqrt{3} }{\sqrt{3900} } =\frac{22\sqrt{39} }{10\sqrt{39} } =\frac{22}{10} =2,2[/tex]
d)[tex]\frac{\sqrt{48} *\sqrt{162} }{\sqrt{72}*\sqrt{135} } =\frac{4\sqrt{3}*9\sqrt{2} }{6\sqrt{2}*3\sqrt{15} } =\frac{36\sqrt{6} }{18\sqrt{30} } =2\sqrt{\frac{6}{30} } =2\sqrt{\frac{1}{5} } =\frac{2}{\sqrt{5} } *\frac{\sqrt{5} }{\sqrt{2} } =\frac{2\sqrt{5} }{5}[/tex]
