You can put this solution on YOUR website!
Since you have provided an \"expresson\" rather than an \"equation\", there is nothing to \"solve\"!
\n" ); document.write( "However, you could simplify the given expression:
\n" ); document.write( " $\"Log%5B9%5D%28x%2Fy%5E4%29%5E2\"$ First, simplify the argument:
\n" ); document.write( " $\"Log%5B9%5D%28x%5E2%2Fy%5E8%29\"$ Now apply the \"quotient rule\" for logarithms: $\"Log%5Bb%5D%28M%2FN%29+=+Log%5Bb%5D%28M%29-Log%5Bb%5D%28N%29\"$ to get:
\n" ); document.write( " $\"Log%5B9%5D%28x%5E2%29-Log%5B9%5D%28y%5E8%29\"$ Now apply the \"power rule\":
\n" ); document.write( " $\"2Log%5B9%5D%28x%29-8Log%5B9%5D%28y%29\"$ \n" ); document.write( "

\n" );
