Answer:

Step-by-step explanation:

Apply rule : ![a^\frac{1}{3}=\sqrt[3]{a}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7B1%7D%7B3%7D%3D%5Csqrt%5B3%5D%7Ba%7D)
![8^\frac{1}{3}=\sqrt[3]{8}](https://tex.z-dn.net/?f=8%5E%5Cfrac%7B1%7D%7B3%7D%3D%5Csqrt%5B3%5D%7B8%7D)
8 is a perfect cube. Evaluate the cube root of 8.
![\sqrt[3]{8}=2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%3D2)
The answer is true, but do you need the formula for it or just the true or false
