Best ResponseYou've already chosen the best response.1\[i^2=1\\(\frac{5}{3} +i)^2=\\\frac{25}{9} +2(\frac{5}{3})(i) +i^2=\\\frac{25}{9}+\frac{10}{3}i 1\]

Best ResponseYou've already chosen the best response.1\[\frac{6+i}{3i}=\\\frac{6+i}{3i}*\frac{3+i}{3+i}=\\=\frac{(6+i)(3+i)}{3^2i^2}=\\\]can you go on ?
