You can put this solution on YOUR website!
$\"4%5E%28t%2B1%29=5%5Et\"$
\n" ); document.write( "(t+1)*log(4) = t*log(5)
\n" ); document.write( "t*log(4) + log(4) = t*log(5)
\n" ); document.write( "t*log(5) - t*log(4) = log(4)
\n" ); document.write( "t*log(5/4) = log(4)
\n" ); document.write( "t = log(4)/log(1.25)
\n" ); document.write( "---------------------
\n" ); document.write( " $\"4%5E%28t%2B1%29=5%5Et\"$
\n" ); document.write( " $\"4%2A4%5Et=5%5Et\"$
\n" ); document.write( " $\"5%5Et%2F4%5Et+=+4\"$
\n" ); document.write( " $\"%281.25%29%5Et+=+4\"$
\n" ); document.write( "Use base change
\n" ); document.write( "t = log(4)/log(1.25)
