a) [tex]\sqrt{3} * \sqrt{5} * \sqrt{15}[/tex] = [tex]\sqrt{3 * 5 * 15}[/tex] = [tex]\sqrt{225}[/tex] = [tex]15[/tex]
b) [tex]\sqrt{\frac{4}{5} } * \sqrt{0,6} * \sqrt{12} = \sqrt{\frac{8}{10} * \frac{6}{10} * \frac{12}{1} } = \sqrt{5\frac{76}{100} } = \sqrt{5,76}[/tex]
c) [tex]\sqrt[3]{\frac{11}{5} } * \sqrt[3]{2,5} * \sqrt[3]{\frac{11}{8} } = \sqrt[3]{\frac{11}{5} * 2\frac{1}{2} * \frac{11}{8} } = \sqrt[3]{\frac{121}{16} } = \sqrt[3]{7\frac{9}{16} }[/tex]
