Question

Вычислите, пожалуйста!

Answer 1

$frac{3^{-1}-(frac{2}{3})^{-2}}{2-(frac{3}{4})^2} cdot (5^0-frac{1}{6})^{-1}+2cdot (10)^{-1}=\\= frac{frac{1}{3}-frac{9}{4}}{2-frac{9}{16}} cdot (1-frac{1}{6})^{-1}+frac{2}{10}=\\= frac{frac{4-27}{12}}{frac{32-9}{16}} cdot (frac{5}{6})^{-1}+frac{1}{5}= frac{-23, cdot ; 16}{12, cdot ; 23} cdot frac{6}{5}+frac{1}{5}= -frac{16}{12} cdot frac{6}{5}+frac{1}{5}=\\= -frac{16}{2cdot 5} +frac{1}{5}= frac{-16+2}{10} =frac{-14}{10}=-1,4$
