Answer:
Step-by-step explanation:
Given complex number is:
To find:
Answer in rectangular form after using De Moivre's theorem = ?
i.e. the form (not in forms of angles)
Solution:
De Moivre's theorem provides us a way of solving the powers of complex numbers written in polar form.
As per De Moivre's theorem:
So, the given complex number can be written as:
Now, using De Moivre's theorem:
So, the answer in rectangular form is:
The math I used is probably not the quickest way, but for me, the easiest.
25*5=125 25+20=45 45*7=315 125+315=440 25*4=100 440+100=540 5+7+4=16
B is your answer.
