5/8=15/x
cross multiply and divide to find x.
8*15=120
120/5=24
You would need 24 drops of yellow
Answer:

Step-by-step explanation:
![[2(\cos15+i15)^{4}]\\=2^{4}(\cos15+i\sin15)^{4}\\=16(\cos15+i\sin15)^{4}..........(1)](https://tex.z-dn.net/?f=%5B2%28%5Ccos15%2Bi15%29%5E%7B4%7D%5D%5C%5C%3D2%5E%7B4%7D%28%5Ccos15%2Bi%5Csin15%29%5E%7B4%7D%5C%5C%3D16%28%5Ccos15%2Bi%5Csin15%29%5E%7B4%7D..........%281%29)
<u>De Moivre's Formula :</u>

Now from eqn(1)
![[2(\cos15+i\sin15)]^{4}=16\times \frac{1+\sqrt{3}i}{2} =8+8\sqrt{3}i](https://tex.z-dn.net/?f=%5B2%28%5Ccos15%2Bi%5Csin15%29%5D%5E%7B4%7D%3D16%5Ctimes%20%5Cfrac%7B1%2B%5Csqrt%7B3%7Di%7D%7B2%7D%20%3D8%2B8%5Csqrt%7B3%7Di)
