a) =0,6*55 + [tex]( \frac{26}{5} )^{2} * 5^{3}[/tex]=

[tex]33+ 26^{2} * 5[/tex]=

[tex]33+ 676*5[/tex]=

[tex]33+ 3380= 3413[/tex]

b) =[tex](\frac{27^{2} }{10^{2} } +\frac{9^{3} }{10^{3} } * 10^{2} ) * \frac{3}{10} =[/tex]

[tex]\frac{27^{2} +9^{3} *10}{10^{2} } * \frac{3}{10} =[/tex]

[tex]\frac{729+ 7290}{100} * \frac{3}{10}[/tex]=

[tex]\frac{8019*3}{1000}[/tex]= 24,057

c) =[tex][\frac{81}{25} - (\frac{289}{100} - \frac{225}{100} ) :8 :0,2]:7,1=[/tex]

[tex](\frac{81}{25} - \frac{64}{100} * \frac{1}{8} :0,2):7,1=[/tex]

[tex](\frac{81}{25} - \frac{8}{100} *\frac{2}{10} ):7,1=[/tex]

[tex](\frac{81}{25} - \frac{64}{1000} ): 7,1=[/tex]

[tex]\frac{81*40-64}{1000} *\frac{71}{10}=[/tex]

[tex]\frac{225*496}{10000} = 22,54[/tex]

d) =[tex]\frac{58}{10} *\frac{1}{2} - \frac{36}{25}=[/tex]

[tex]\frac{29}{10} -\frac{36}{25} =[/tex]

[tex]\frac{29*5-36*2}{50} =\\\frac{145-72}{50} =\\\frac{73}{50} = 1,46[/tex]
