2/5=0.4
0.4*11.25=4.5
Step-by-step explanation:
Hello:
<span>cube root 64(cos330+isin330) iz the complex number with :
z^3 =</span><span> 64(cos330+isin330) ...(1)
let: z = r(cos(</span>θ) +isin(<span>θ))
so : z^3 = r^3 (</span>cos(3θ) +isin(3θ))...(2) ( by moivre)
by(1) and (2) :
r^3 =64 = 4^3 and 3θ =11π/6 +2k<span>π.... k=0 , 1 , 2
</span>r =4 and θ = 11π/18 +2kπ/3 ..... k=0 , 1 , 2
coclusion : 3 <span>cube root ....calculate if k = 0 , 1 , 2</span>
