$\"x%5E%281%2F3%29+=+8\"$ Start with the given equation\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28x%5E%281%2Fcross%283%29%29%29%5Ecross%283%29+=+8%5E3\"$ Cube both sides. This will cancel out the exponent of $\"1%2F3\"$ \r
\n" ); document.write( "

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x+=+512\"$ Cube 8 to get 512 \n" ); document.write( "
