\n" ); document.write( " $\"9a%5E5%2F3a%5E7\"$
\n" ); document.write( ".
\n" ); document.write( "We can simplify the coefficients since 9 divided by 3 is 3.
\n" ); document.write( " $\"3a%5E5%2Fa%5E7\"$
\n" ); document.write( ".
\n" ); document.write( "We can simplify a^5/a^7. Remember, when you divide exponential expresisons, you subtract the exponents; 5-7=-2
\n" ); document.write( " $\"3a%5E-2\"$
