We need the exponents law
![a^{bx}=(a^b)^x](https://tex.z-dn.net/?f=a%5E%7Bbx%7D%3D%28a%5Eb%29%5Ex)
So if
a=3
b=1/2
then
![3^{1/2*x}=(3^{1/2})^x](https://tex.z-dn.net/?f=3%5E%7B1%2F2%2Ax%7D%3D%283%5E%7B1%2F2%7D%29%5Ex)
where x represent every half a year.

Answer:
160°
Step-by-step explanation:
-Given the angle in radians as ![\theta=\dfrac{8\pi}{9}\ rad](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cdfrac%7B8%5Cpi%7D%7B9%7D%5C%20rad)
-We know that ![1 \ rad=\frac{180}{\pi}\textdegree](https://tex.z-dn.net/?f=1%20%5C%20rad%3D%5Cfrac%7B180%7D%7B%5Cpi%7D%5Ctextdegree)
-Let our angle theta be X
#We therefore equate and cross multiply:
![1\ rad=\frac{180}{\pi}\\\\\frac{8\pi}{9}=x\\\\\therefore X=\frac{180}{\pi}\times \frac{8\pi}{9}\\\\=160\textdegree](https://tex.z-dn.net/?f=1%5C%20rad%3D%5Cfrac%7B180%7D%7B%5Cpi%7D%5C%5C%5C%5C%5Cfrac%7B8%5Cpi%7D%7B9%7D%3Dx%5C%5C%5C%5C%5Ctherefore%20X%3D%5Cfrac%7B180%7D%7B%5Cpi%7D%5Ctimes%20%5Cfrac%7B8%5Cpi%7D%7B9%7D%5C%5C%5C%5C%3D160%5Ctextdegree)
Hence, angle θ is 160°
