Answer:
(9-57i)
Step-by-step explanation:
We need to find the product of the given complex number i.e.
(3-9i)(6-i)
It can be solved as follows :
(3-9i)(6-i) = 3(6) +3(-i) +(-9i)(6) + 9i(i)
= 18-3i-54i+9i²
We know that, i² = -1
So,
= 18-3i-54i+9(-1)
= 18-57i-9
= 9-57i
So, the product of the given complex number is (9-57i).
