You can put this solution on YOUR website!
3 cuberoot(x)- 4 = 2
\n" ); document.write( " 3 cubert(x) = 2 + 4
\n" ); document.write( " 3 cubert(x) = 6
\n" ); document.write( "Cube both sides and you have:
\n" ); document.write( "27x = 216
\n" ); document.write( "x = 216/27
\n" ); document.write( "x = 8
\n" ); document.write( ":
\n" ); document.write( "Check solution: we know the cube root of 8 = 2
\n" ); document.write( "(3 * 2) - 4 = 2
\n" ); document.write( " \n" ); document.write( "

\n" );
