\([ (\frac{1}{5}+\frac{7i}{5})-(6+\frac{i}{5})]-\rm (\frac{-4}{5}+i)\)
= \(\rm (\frac{1}{5}-6+\frac{7i}{5}-\frac{i}{5})-\rm (\frac{-4}{5}+i)\)
= \(\rm (\frac{-29}{5}+\frac{6i}{5})-\rm (\frac{-4}{5}+i)\)
= \(\rm (\frac{-29}{5}+\frac{4}{5}+\frac{6i}{5}-i)\)
= \(\rm (\frac{-25}{5}+\frac{i}{5})\)
= \(\rm (-5+\frac{i}{5})\)
