Answer:
![((\frac{2}{3})^0)^{-3}=1](https://tex.z-dn.net/?f=%28%28%5Cfrac%7B2%7D%7B3%7D%29%5E0%29%5E%7B-3%7D%3D1)
Step-by-step explanation:
We need to find the value of ![((\frac{2}{3})^0)^{-3}](https://tex.z-dn.net/?f=%28%28%5Cfrac%7B2%7D%7B3%7D%29%5E0%29%5E%7B-3%7D)
Solving:
We know, ![(a^b)^n = a^{b*n}](https://tex.z-dn.net/?f=%28a%5Eb%29%5En%20%3D%20a%5E%7Bb%2An%7D)
![((\frac{2}{3})^{0*-3})](https://tex.z-dn.net/?f=%28%28%5Cfrac%7B2%7D%7B3%7D%29%5E%7B0%2A-3%7D%29)
![(\frac{2}{3})^0](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B3%7D%29%5E0)
a^0 = 1
so,
![(\frac{2}{3})^0=1](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B3%7D%29%5E0%3D1)
So, the value of ![((\frac{2}{3})^0)^{-3}=1](https://tex.z-dn.net/?f=%28%28%5Cfrac%7B2%7D%7B3%7D%29%5E0%29%5E%7B-3%7D%3D1)
Answer:
8 = b - 1 + 8b
group like terms
8 + 1 = b + 8b
9 = 9b cus b standing alone me 1b
divide both side by 9
<u>9</u><u> </u> = <u>9</u><u>b</u>
9 9
b = 1
