-2\"+root%283%2C16y%5E4%29+-+root%283%2C27y%5E8%29+%2B+root%283%2C81%29+\"
\n" ); document.write( " *except all of the roots are not squared, they are cubed.*
\n" ); document.write( "It's cube root, not cubed root.
\n" ); document.write( "---------------
\n" ); document.write( " -2\"+root%283%2C8y%5E3%2A2y%29+-+root%283%2C27y%5E6%2Ay%5E2%29+%2B+root%283%2C27%2A3%29+\"
\n" ); document.write( "= -2\"+2y%2Aroot%283%2C2y%29+-+3y%5E2%2Aroot%283%2Cy%5E2%29+%2B+3root%283%2C3%29+\"
