\"log%283%2C%28x%29%29-4log%283%2C%283y%29%29\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"log%283%2C%28x%29%29-log%283%2C%28%283y%29%5E4%29%29\" Rewrite the second logarithm using the identity \"y%2Alog%28b%2C%28x%29%29=log%28b%2C%28x%5Ey%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"log%283%2C%28%28x%29%2F%283y%29%5E4%29%29\" Combine the logs using the identity \"log%28b%2C%28A%29%29-log%28b%2C%28B%29%29=log%28b%2C%28A%2FB%29%29\"\r

\n" ); document.write( "\n" ); document.write( "\"log%283%2C%28%28x%29%2F%2881y%5E4%29%29%29\" Expand and simplify\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"log%283%2C%28x%29%29-4log%283%2C%283y%29%29\" simplifies to \"log%283%2C%28%28x%29%2F%2881y%5E4%29%29%29\"
