10)( 1 - 4i ) + ( 1 + 7i ) = 1 - 4i + 1 + 7i = 2 + 3i;

11)( - 1 - 3i ) - ( - 2 + 2i ) = - 1 - 3i + 2 - 2i = 1 - 5i;

12)( 3 + 4i ) * ( 3 - 2i ) = 3 * 3 + 3 * ( - 2i ) + 4i * 3 + 4i * ( - 2i ) = 9 - 6i + 12i - 8i = 9 - 2i;

13)( 1 + 3i ) / ( - 2 - i ) = ( 1 + 3i ) * ( - 2 + i ) / ( - 2 - i ) * ( - 2 + i ) = ( - 2 + i - 6i + 3i ^ 2 ) / ( - 2 - i ) * ( - 2 + i ) = ( - 2 - 5i + 3i ^ 2 ) / ( 4 - i ^ 2 ) = ( - 2 - 5i + 3 ) / 4 = ( 1 - 5i ) / 4;

14)( 3 + 2i ) ^ 3 = 3 ^ 3 + 3 * 3 ^ 2 * 2i + 3 * 3 * ( 2i ) ^ 2 + ( 2i ) ^ 3 = 27 + 54i + 36i ^ 2 + 8i ^ 2 = 27 + 54i + 44i ^ 2.
