$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: 36 + 23 i$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: (3 + 8i)(4 - 3i)$

$\qquad \tt \rightarrow \: (3 \sdot 4)+ (3 \sdot - 3i) + (8i \sdot4) + (8i \sdot - 3i)$

$\qquad \tt \rightarrow \: 12 - 9i + 32i - (24 {i}^{2} )$

$\qquad \tt \rightarrow \: 12 + 23i -( 24 \sdot - 1)$

$\qquad \tt \rightarrow \: 12 + 23i + 24$

$\qquad \tt \rightarrow \: 36 + 23i$
