/ / ____\ \ x1 = I*\- log\2 - I*\/ 21 / + log(5)/
$$x_{1} = i \left(\log{\left(5 \right)} - \log{\left(2 - \sqrt{21} i \right)}\right)$$
/ / ____\ \ x2 = I*\- log\2 + I*\/ 21 / + log(5)/
$$x_{2} = i \left(\log{\left(5 \right)} - \log{\left(2 + \sqrt{21} i \right)}\right)$$
x2 = i*(log(5) - log(2 + sqrt(21)*i))
