document.write( "(-1)(-1)(-1)=(-1)^-1, both sides equal -1\r\n" );

document.write( "Note that 0 is NOT a solution since 0^0 is not defined.\r\n" );
document.write( "Note also that -3 is not a solution, since (-3)(-3)(-3) is -27,\r\n" );
document.write( "but (-3)^(-3) is -1/27.\r\n" );

document.write( "So the solution set is {-1, 1, 3}\r\n" );
