When everything is multiplied you can add/subtract the exponents of like terms (all x's, all y's). Subtract the exponent in the denominator from the exponent in the numerator (divide like terms with exponents is the same as subtracting the exponent in the denominator):

\n" ); document.write( " $\"x%5E%28-1-%28-4%29%29+=+x%5E3\"$ and $\"y%5E%28-3-%28-3%29%29+=+y%5E0+=+1\"$ . So this becomes:\r
\n" ); document.write( "\n" ); document.write( " $\"%28-16+%2A+x%5E3+%2A+-1+%2A+1%29+%2F+80\"$ = $\"16x%5E3+%2F+80\"$ = $\"x%5E3+%2F+5\"$ \n" ); document.write( "

\n" );
