Solve for b (complex solution)
b=\frac{2\times 5^{\frac{4}{5}}\sqrt[5]{3}e^{\frac{2\pi i}{5}}}{5}\approx 0.558010807+1.717380674i
b = \frac{2 \cdot 5 ^ {\frac{4}{5}} \sqrt[5]{3}}{5} \approx 1.805760903
b=\frac{2\times 5^{\frac{4}{5}}\sqrt[5]{3}e^{\frac{4\pi i}{5}}}{5}\approx -1.460891258+1.061399628i
b=\frac{2\times 5^{\frac{4}{5}}\sqrt[5]{3}e^{\frac{6\pi i}{5}}}{5}\approx -1.460891258-1.061399628i
b=\frac{2\times 5^{\frac{4}{5}}\sqrt[5]{3}e^{\frac{8\pi i}{5}}}{5}\approx 0.558010807-1.717380674i
