\n" ); document.write( "Probably the easiest place to start is with \"ac%5E3=135\". The prime factorization of 135 is \"135+=+3%2A3%2A3%2A5\"; that means a=5 an c=3.

\n" ); document.write( "Then \"a%5E3b+=+5%5E3%2Ab+=+125b+=+1375\" so b is 11.

\n" ); document.write( "Then a+b+c = 5+11+3 = 19.
\n" ); document.write( "
\n" );
