Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as

Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles as
A+B = 63+117 =180

=
Since sin180=0 and cos 180=-1
You need to move the decimal point to be at 1.
Since this is a decimal, the power will be negative.
I had to move the decimal 6 places.
So,
1^-6

Answer:
The answer would be - 11.
Step-by-step explanation:
9 + 8 = 17
17 - 6 = 11.
4 - 5 = 4 + - 5 = - 1
11(- 1) = 11 × - 1 = - 11
Therefor, your answer would be - 11.
Hope this helps!
