From the de Moivre's we have,
<span>
(cosθ+isinθ)^n=cos(nθ)+isin(nθ)
</span><span>
Therefore,
</span><span>
R((cosθ+isinθ)^5)=cos(5θ)I((cosθ+isinθ)^5)=sin(5θ)
</span><span>
Simplifying,
</span><span>
cos^5(θ)−10(sin^2(θ))(cos^3(θ))+5(sin^4(θ))(cosθ)=cos(5θ) </span><span>

Answer: 8.5
17/0.50 is 8.5
17-8.5
We will round both numbers:-
9.1 = 9
11.8 = 12
Now we will multiply these 2 numbers to get our answer.
9 × 12 = 108
So, 9.1 ÷ 11.8 is ABOUT 108.
Hope I helped ya!!!!!!!
Yes, it isn’t a fraction, decimal, or mixed number.
80 1.5 because 10 times 8 equals 80 plus 1.5 equals 80.1.5
