First, distribute the terms:
(i63 + i17 + i13 + i82)(i72 - i34) = i63i72 + i63(-i34) + i17i72 + i17(-i34) + i13i72 + i13(-i34) + i82i72 + i82(-i34)
Simplify each term:
i63i72 = -4536i63(-i34) = -2142ii17i72 = 1224ii17(-i34) = -578ii13i72 = 936ii13(-i34) = -442ii82i72 = 5904ii82(-i34) = -2788i
Combine like terms:
-4536 + 1224i - 442i + 5904i - 2142i - 578i - 2788i= -4536 - 2198i
Therefore, (i63 + i17 + i13 + i82)(i72 - i34) simplifies to -4536 - 2198i.

Combine like terms:
-4536 + 1224i - 442i + 5904i - 2142i - 578i - 2788i
= -4536 - 2198i
Therefore, (i63 + i17 + i13 + i82)(i72 - i34) simplifies to -4536 - 2198i.
