You can put this solution on YOUR website!
You have three denominators :m^2, n and m
\n" ); document.write( "Clearly m is a factor of m^2
\n" ); document.write( "so the common denominator will be nm^2
\n" ); document.write( "so multiply the fraction with m^2 as the denominator by n/n
\n" ); document.write( "the n denominator by m^2/m^2
\n" ); document.write( "the m denominator by mn/mn
\n" ); document.write( "The parts with no denominator by nm^2/nm^2
\n" ); document.write( "nm^4 +n^3 -m^2*n^4 +nm^3- nm^3+ m^2n^2+m^2n^2
\n" ); document.write( "now combine terms
\n" ); document.write( "nm^4-m^2n^4+n^3+2m^2n^2
\n" ); document.write( "All over nm^2
\n" ); document.write( " \n" ); document.write( "

\n" );
