You can put this solution on YOUR website!
ignoreing the words base2 for sake of clarity:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"+3log%285x%29=+12+\"$
\n" ); document.write( " $\"+log%285x%29=+4+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, to reverse log-base2 we need to raise both sides as follows:
\n" ); document.write( " $\"+2%5E%28log%285x%29%29+=+2%5E4+\"$
\n" ); document.write( " $\"+5x+=+16+\"$
\n" ); document.write( " $\"+x+=+16%2F5+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "jon.
