$\"%289z%5E3%29%2F%2811r%5E2%29\"$ * $\"%28121r%5E4%29%2F%2881z%29\"$
\n" ); document.write( ":
\n" ); document.write( "Much easier if you cancel, then multiply
\n" ); document.write( "11r^2 into 121r^4 and 9 into 81 and z into z^3
\n" ); document.write( ":
\n" ); document.write( " $\"z%5E2\"$ * $\"%2811r%5E2%29%2F9\"$ = $\"%2811r%5E2z%5E2%29%2F9\"$ \n" ); document.write( "
