[latex] sqrt{( frac{2}{12} + frac{3}{15}):( frac{1}{8} + frac{7}{40})-( frac{1}{3})^3* sqrt{ sqrt{16* sqrt{81^2} } } } = \ =sqrt{( frac{5}{30}+ frac{6}{30}):( frac{5}{40}+ frac{7}{40})- frac{1}{27}* sqrt{ sqrt{16*81} } } = \ = sqrt{ frac{11}{30} : frac{12}{40}- frac{1}{27} * sqrt{36} } = \ = sqrt{ frac{11}{30} * frac{40}{12} -frac{1}{27}*6 } = sqrt{ frac{440}{360}- frac{6}{27} } = sqrt{ frac{11}{9}- frac{2}{9} } = sqrt{ frac{9}{9} } =1[/latex] [latex] sqrt{ frac{3}{4}:( frac{1}{3}+1) } + sqrt{ frac{1}{2}:2*( frac{3}{2} )^2 } - sqrt{ frac{9}{4} }= \ = sqrt{frac{3}{4}:frac{4}{3}} + sqrt{ frac{1}{4}* frac{9}{4} } - frac{3}{2} = sqrt{ frac{9}{16} } +sqrt{ frac{9}{16} } -frac{3}{2}= frac{3}{4} +frac{3}{4} -frac{3}{2}= frac{6}{4} -frac{6}{4} =0[/latex]
