The key is to break up whatever you can into cube roots


root%283%2C8x%5E2y%5E3z%5E4%29


root%283%2C8%29%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cy%5E3%29%2Aroot%283%2Cz%5E4%29


root%283%2C2%5E3%29%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cy%5E3%29%2Aroot%283%2Cz%5E4%29


2%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cy%5E3%29%2Aroot%283%2Cz%5E4%29


2%2Aroot%283%2Cx%5E2%29%2Ay%2Aroot%283%2Cz%5E4%29


2%2Ay%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cz%5E4%29


2%2Ay%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cz%5E3%2Az%29


2%2Ay%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cz%5E3%29%2Aroot%283%2Cz%29


2%2Ay%2Aroot%283%2Cx%5E2%29%2Az%2Aroot%283%2Cz%29


2%2Ay%2Az%2Aroot%283%2Cx%5E2%29%2Aroot%283%2Cz%29


2yz%2Aroot%283%2Cx%5E2z%29


==============================================================================================================


So, root%283%2C8x%5E2y%5E3z%5E4%29 simplifies to 2yz%2Aroot%283%2Cx%5E2z%29
