a) [tex]\sqrt{3 * 5 * 15} = \sqrt{15*15} = \sqrt{15^{2} } = 15[/tex]
b) [tex]\sqrt{\frac{4}{5}* \frac{3}{5} * 12} = \sqrt{\frac{12}{25} * 12} = \sqrt{\frac{12^{2} }{5^{2}} } } = \frac{12}{5} } = 2\frac{2}{5} = 2,4[/tex]
c) [tex]\sqrt[3]{1\frac{1}{5}* 2\frac{1}{2}* 1\frac{1}{8} } = \sqrt[3]{\frac{6}{5}*\frac{5}{2}*\frac{9}{8} } = \sqrt[3]{\frac{6}{2} * \frac{9}{8} } = \sqrt[3]{\frac{54}{16} } = \sqrt[3]{\frac{2 * 27}{2*8} } = \sqrt[3]{\frac{27}{8} } =\frac{3}{2} = 1\frac{1}{2} =[/tex]
[tex]= 1,5[/tex]
