[tex]\frac{\sqrt[3]{27} -0,3^{-2} }{(\sqrt{46})^{2} -(-3)^{-3} } =\frac{3-(\frac{3}{10})^{-2} }{46-(-\frac{1}{27}) } =\frac{3-\frac{100}{9} }{46+\frac{1}{27} } =(-\frac{73}{9} ):\frac{1243}{27}=\\\\= (-\frac{73}{9} )*\frac{27}{1243} =-\frac{73*3}{1243} =-\frac{219}{1243}[/tex]
[tex]\frac{2\frac{5}{6}-1^{-1,5} }{\sqrt[3]{-64}-\sqrt{49} } =\frac{\frac{17}{6}-1 }{-4-7}=\frac{\frac{11}{6} }{-11} =\frac{11}{6}*(-\frac{1}{11})=-\frac{1}{6}[/tex]
