Basically each part of the first complex number gets multiplied by each part of the second complex number. You are multiplying 2 binomials.
(15 + 56i(7 + 4i)
= 105 + 60i + 392i + 224i^2
= 105 + 452i - 224 ( because i^2 = -1)
= - 119 + 452i
Answer:
.225

Answer:
I think its x not = 4 because that would make the denominator = 0 after the multiplication. (g x h = 2x - 8 / x - 4
Step-by-step explanation:
4 1/3+7 2/4=4+1/3+7+1/2=11+(1/3+1/2)=11 5/6. For some reason, the fact that the question said 7 2/4 instead of 7 1/2 suggests that you may have misread the problem.
