Answer:
<h2>
![7 \sqrt[3]{2x}  - 6 \sqrt[3]{2x}  - 6x](https://tex.z-dn.net/?f=7%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%206%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%206x)
</h2>
Solution,
![7( \sqrt[3]{2x} ) - 3( \sqrt[3]{16x} ) - 3( \sqrt[3]{8x} ) \\  = 7 \sqrt[3]{2x}  - 3 \times ( \sqrt[3]{2 \times 2 \times 2 \times 2x}  - 3 \times  \sqrt[3]{2 \times 2 \times 2x}  \\  = 7 \sqrt[3]{2x}  - 3 \times (2 \sqrt[3]{2} x) - 3 \times 2x \\  = 7 \sqrt[3]{2x}  - 3 \times 2 \times  \sqrt[3]{2x}  - 3 \times 2x \\  = 7 \sqrt[3]{2x}  - 6 \sqrt[3]{2x}  - 6x](https://tex.z-dn.net/?f=7%28%20%5Csqrt%5B3%5D%7B2x%7D%20%29%20-%203%28%20%5Csqrt%5B3%5D%7B16x%7D%20%29%20-%203%28%20%5Csqrt%5B3%5D%7B8x%7D%20%29%20%5C%5C%20%20%3D%207%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%203%20%5Ctimes%20%28%20%5Csqrt%5B3%5D%7B2%20%5Ctimes%202%20%5Ctimes%202%20%5Ctimes%202x%7D%20%20-%203%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%5Ctimes%202%20%5Ctimes%202x%7D%20%20%5C%5C%20%20%3D%207%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%203%20%5Ctimes%20%282%20%5Csqrt%5B3%5D%7B2%7D%20x%29%20-%203%20%5Ctimes%202x%20%5C%5C%20%20%3D%207%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%203%20%5Ctimes%202%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%203%20%5Ctimes%202x%20%5C%5C%20%20%3D%207%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%206%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%206x)
