7 - 24i
Explanation:
(4−3i)(4−3i)(4-3i)(4-3i).
(4−3i)(4−3i)(4-3i)(4-3i)
Expand (4−3i)(4−3i)(4-3i)(4-3i) using the FOIL Method.
Apply the distributive property.
4(4−3i)−3i(4−3i)4(4-3i)-3i(4-3i)
Apply the distributive property.
4⋅4+4(−3i)−3i(4−3i)4⋅4+4(-3i)-3i(4-3i)
Apply the distributive property.
4⋅4+4(−3i)−3i⋅4−3i(−3i)4⋅4+4(-3i)-3i⋅4-3i(-3i)
