$\"4log%28x%29-3log%28%28x%5E2%2B1%29%29%2B2+log%28x-1%29\"$
\n" ); document.write( "All these logs are base 10 we know this because logs base 10 dont need to show the 10 like log base 7 or log base 3 would. It just shows log.
\n" ); document.write( "If there is a number before the log it is an exponent.
\n" ); document.write( "The above equation can be written
\n" ); document.write( " $\"log%28x%5E4%29-log%28%28x%5E2%2B1%29%5E3%29%2Blog%28%28x-1%29%5E2%29\"$
\n" ); document.write( "Now we will use the division/multiplication property..
\n" ); document.write( " $\"log%28%28%28x%5E4%29%28x-1%29%5E2%2F%28%28x%5E2%2B1%29%5E3%29%29%29\"$
\n" ); document.write( "When there is a minus sign before the log it is on the bottom. If there is a plus before the log it goes on top.
\n" ); document.write( " \n" ); document.write( "

\n" );
