sorry, że potęgi słownie ale inaczej nie umiem ;- ).

$a) 1\frac{4}{5}- 3\frac{2}{7} * 5\frac{5}{13} =\frac{9}{5}-\frac{23}{7}*\frac{70}{13}=\frac{9}{5}-\frac{230}{13}=\frac{117-1150}{65}=-\frac{1033}{65}=-15\frac{58}{65}$

$b) (0,4 + 1\frac{2}{3}) * (-2)^{2} =(\frac{2}{5}+\frac{5}{3})*4=(\frac{6+25}{15})*4=\frac{31}{15}*4=\frac{124}{15}=8\frac{4}{15}$

$c) (2\frac{3}{4} - 3,5) * (-(2^{2})) =(\frac{11}{4}-\frac{7}{2})*(-4)=(\frac{11-14}{4})*(-4)=3$

$d) [2\frac{1}{4} + (-\frac{1}{2})^{2}] ^{2} =[\frac{9}{4}+\frac{1}{4}]^2=(\frac{10}{4})^2=\frac{100}{16}=6\frac{1}{4}$

$e) [0,75 - (-\frac{3}{4})^{2}] ^{2} =(\frac{3}{4}-\frac{9}{16})^2=(\frac{12-9}{16})^2=(\frac{3}{16})^2=\frac{9}{256}=$
