Information about iota :

$\bold{\boxed{i = \sqrt{ - 1} }}$

$\bold{\boxed{ {i}^{2} = 1}}$

$\bold{\boxed{{i}^{3} =i \times {i}^{2} = > - i}}$

$\bold{\boxed{{i}^{4} = 1}}$

Now come to the question:

$= > (3 - 2i)(6 - 8i)$

$= > 3(6 - 8i) - 2i(6 - 8i)$

$= > 18 - 24i - 12i + 16 {i}^{2}$

$= > 18 - \sqrt{ - 24} - \sqrt{ - 12} + 16$

$= > 18 - 2 \sqrt{ - 6} - 2 \sqrt{ - 3} + 16$

$= > 18 - 2( \sqrt{ - 6} + \sqrt{ - 3} ) + 16$

$= > 34 - 2( \sqrt{ - 6} + \sqrt{ - 3} )$
