6 sqrt sign 49a and small 9 at top ofa -5 sqrt sign 36b and small 2 at top of b
\n" ); document.write( "------------
\n" ); document.write( "6sqrt(49a^9) - 5sqrt(36b^2)\r
\n" ); document.write( "\n" ); document.write( "= 6sqrt(49a^8)sqrt(a) - 5*6b\r
\n" ); document.write( "\n" ); document.write( "= 6*7a^4*sqrt(a) - 30b\r
\n" ); document.write( "\n" ); document.write( "= 42a^4(sqrt(a)) - 30b\r
\n" ); document.write( "\n" ); document.write( "==============================
