Answer» ` ((1 + i) ^ 3 )/( 4 + 3 i ) = (1 ^ 3 + 3. 1 ^ 2 . i + 3 . 1 + i ^ 2 + i ^ 3 ) /( 4 + 3i ) = ( 1 + 3i - 3 - i ) /( 4 + 3i ) ` ` = ( - 2 + 2 i ) /( 4 + 3 i ) = (( - 2 + 2 i ) ( 4 - 3 i ) ) /( ( 4 + 3i ) ( 4 - 3i)) ` ` = ( - 8 + 8i + 6i - 6i ^ 2 ) /( 4 ^ 2 - 9 i^ 2 ) = ( - 2 + 14 i ) /( 25 ) = - ( 2 ) /( 25 ) + i ( 14 ) /( 25 ) ` |
