the answer is f18ab2<span> • sqrt(oa) </span>
a.
b. Not exactly sure how DeMoivre's theorem is relevant, since it has to do with taking powers of complex numbers... At any rate, multiplying and is as simple as multiplying the moduli and adding the arguments:
c. Similar to (b), except now you divide the moduli and subtract the arguments:
Multiply 9 by 2
18 = 4
Then subtract 4 from both sides
18 - 4 = 0 will become
14 = 0
Since 14 ≠ 0, there are no solutions
