[tex]a)\\4^{9} * \frac{1}{8} ^{9} : \frac{1}{2} ^{7} = 4^{9} * 8^{-9} : 2^{-7} = (2^{2} )^{9} * (2^{3}) ^{-9}: 2^{-7} = 2^{18} * 2^{-27}: 2^{-7}= 2^{-2} = \frac{1}{4}[/tex]

[tex]b)\\\frac{(\frac{1}{5}) ^{9} : (\frac{4}{25}) ^{9} }{1,25^{8} } = \frac{(\frac{1}{5} : \frac{4}{25}) ^{9} }{1,25^{8}} = \frac{(\frac{1}{5} * \frac{25}{4} )^{9} }{1,25^{8}} = \frac{1,25^{9}}{1,25 ^ {8}} = 1,25[/tex]
