Answer 1

Answer:

$\huge \fcolorbox{black}{cyan}{♛answer♛} \\ \small\bold\red{ (\sqrt{6} + 5i) (\sqrt{6 } - \frac{i}{5}) } \\ \small\bold\red{ = 6 - \frac{ \sqrt{6} }{5} i + 5 \sqrt{6} i - {i}^{2} } \\ \small\bold\red{ = 6 + 1 + i(5 \sqrt{6} - \frac{ \sqrt{6} }{5}) } \\ \small\bold\red{ = 7 + \sqrt{6} i( \frac{25 - 1}{5}) } \\ \small\bold\red{ = 7 + \frac{24}{5} \sqrt{6} i}$
