Question

даю 36 балов только решите умоляю номер 4

Answer 1

$= frac{97 * frac{36+61}{36}:36 }{( frac{4}{9} + frac{1}{ frac{4}{9}} )^2} * frac{4}{10} = frac{ frac{97*97}{36*36}}{( frac{4}{9}+ frac{9}{4})^2 } * frac{4}{10} = frac{ (frac{97}{36} )^2}{ (frac{16+81}{36})^2 } * frac{4}{10} = frac{ (frac{97}{36} )^2}{ (frac{97}{36} )^2} * frac{4}{10}= frac{4}{10} = 0,4$

* 0,(4)=$frac{4}{9}$
