Answer:
D) ![(\sqrt[4]{2x -8} )^4 = (-\sqrt[4]{2x + 8} )^4](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B2x%20-8%7D%20%29%5E4%20%3D%20%28-%5Csqrt%5B4%5D%7B2x%20%2B%208%7D%20%29%5E4)
Step-by-step explanation:
The given equation is ![\sqrt[4]{2x - 8} + \sqrt[4]{2x + 8 } = 0](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2x%20-%208%7D%20%20%2B%20%5Csqrt%5B4%5D%7B2x%20%2B%208%20%7D%20%3D%200)
Before, solve this equation, we have to get rid off the radical sign.
So we move the second term on the other side.
![\sqrt[4]{2x-8} = -\sqrt[4]{2x + 8}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2x-8%7D%20%3D%20-%5Csqrt%5B4%5D%7B2x%20%2B%208%7D)
Since we have to radical of 4, we need to raise the power to 4 on both sides
![(\sqrt[4]{2x - 8)} )^4 = (-\sqrt[4]{2x + 8} )^4\\](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B2x%20-%208%29%7D%20%29%5E4%20%3D%20%28-%5Csqrt%5B4%5D%7B2x%20%2B%208%7D%20%29%5E4%5C%5C)
