Explicación paso a paso:

a)

$\frac{-(\frac{5}{8} -\frac{3}{4} -\frac{2}{4}-(-\frac{-3}{-4} ))*(-\frac{1}{3} )}{(-\frac{2}{3}-\frac{5}{3}-\frac{9}{27} )+(\frac{-3}{-9})^{2} }$

= $\frac{-(\frac{5}{8} -\frac{3}{4} -\frac{2}{4}+\frac{3}{4} )*(-\frac{1}{3} )}{(-\frac{2}{3}-\frac{5}{3}-\frac{9}{27} )+(\frac{3^{2} }{9^{2} }) }$

= $\frac{-(\frac{5-6-4+6}{8} )*(-\frac{1}{3} )}{(\frac{-18-45-9}{27} )+(\frac{9} {81}) } }$

= $\frac{-(\frac{1}{8} )*(-\frac{1}{3} )}{(\frac{-72}{27} )+(\frac{1} {9}) } }$

= $\frac{\frac{1}{24} }{(\frac{-72}{27} )+(\frac{1} {9}) } }$

= $\frac{\frac{1}{24} }{(\frac{-72+3}{27} ) } }$

=$\frac{\frac{1}{24} }{\frac{-69}{27} } }$

=$- \frac{27}{1656}$

= $-\frac{3}{184}$

b)

$-log_{3} 27 -log_{10} (\frac{1000}{10000} )+\frac{\sqrt{\frac{81}{64} } }{\sqrt[3]{\frac{64}{8}} }$

= $-3-(-1)+\frac{\frac{9}{8} }{\frac{4}{2} }$

= $-2+\frac{18}{32}$

=$-\frac{23}{16}$

c)

$-(-log_{2} Log10000)+3^{-2} *3^{2} +(-3-2-1)\\= 2+(\frac{1}{9} *9)+(-6)\\=2+1-6\\=-3$

d)

$\frac{(-\frac{3}{5} +\frac{2}{4}-\frac{1}{5} )*(-\frac{1}{2} )}{\frac{\frac{-3}{-5}}{\frac{-2}{3}} }$

$=\frac{\frac{-12+10-4}{20} *(-\frac{1}{2}) }{\frac{-9}{10} }$

$=\frac{\frac{-6}{20}*(-\frac{1}{2} )}{-\frac{9}{10} }$

$=\frac{\frac{6}{40}}{-\frac{9}{10} }$

$=-\frac{60}{360}$

$=-\frac{1}{6}$
