\r\n" );
document.write( "It helps if you know things like 4ł=64 and ∛64 = 4 \r\n" );
document.write( "\r\n" );
document.write( "Positive fractions can be written as radicals, but\r\n" );
document.write( "negative exponents can't, so we have to put 1 over\r\n" );
document.write( "them with a positive exponent.  Then we use the \r\n" );
document.write( "\"fraction exponential to radical\" rule, which is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now we use the \"fraction exponent to radical\" rule\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "and since we know that ∛64 = 4\r\n" );
document.write( "\r\n" );
document.write( "that becomes\r\n" );
document.write( "\r\n" );
document.write( " \r\n" );
