Răspuns:

$1)\: |\frac{1}{2} |^{2} +\frac{7}{6}= (\frac{1}{2} )^{2} +\frac{7}{6}=^{3)} \frac{1}{4} +\:^{2)} \frac{7}{6}=\frac{3+14}{12}=\frac{17}{12}$

$2)\:250\times|\frac{1}{5} |^{3} +\frac{2}{4}= 250\times\frac{1}{125} +\frac{2}{4}=2+\frac{2}{4}=2+\frac{1}{2} =\frac{4+1}{2}=\frac{5}{2}$

$3)\:\frac{10}{9} -|\frac{1}{3} |^{3} \times\frac{2}{6} =\frac{10}{9} -(\frac{1}{3}) ^{3} \times\frac{1}{3}=\frac{10}{9}-(\frac{1}{3} ) ^{4} = \:^{9)} \frac{10}{9}-\frac{1}{81}= \frac{90-1}{81}=\frac{89}{81}$

$4)\:|\frac{5}{4} |^{2} :|\frac{1}{2} |^{3} =\frac{25}{16} :\frac{1}{8}= \frac{25}{16}\times8=\frac{25}{2}$
