Answer 2

Answer:

$\frac{ -7i}{\sqrt{2} }$     is the correct answer.

Step-by-step explanation:

$\frac{(3 + i \sqrt{5} ) ( 3 - i\sqrt{5} )}{( \sqrt{3} +\sqrt{2} i ) - (\sqrt{3} - i\sqrt{2} )}$      =       $\frac{9 - 3\sqrt{5} i + 3\sqrt{5} i - 5i^{2} }{ 2\sqrt{2} i}$

=     $\frac{9 + 5}{2\sqrt{2}i }$     =   $\frac{7}{\sqrt{2} i} * \frac{\sqrt{2} i}{\sqrt{2}i }$       =     $\frac{7\sqrt{2}i }{2 i^{2} }$      =     $\frac{ -7i}{\sqrt{2} }$

Hope you understand it !!!!!!!!
