I'm not certain what you mean by \"expanded notation\" but I suspect that it means \"raised to the power of\", so, with that in mind, let's proceed...
\n" ); document.write( "\"5%5Ex+=+72\" Take the logarithm of both sides.
\n" ); document.write( "\"Log%285%5Ex%29+=+Log%2872%29\" Apply the power rule for logarithms to the left side:\"Log%5Bb%5D%28M%5Ep%29+=+p%2ALog%5Bb%5D%28M%29\".
\n" ); document.write( "\"x%2ALog%285%29+=+log%28%2872%29%29\" Divide both sides by log(5).
\n" ); document.write( "\"x+=+log%28%2872%29%29%2FLog%285%29\"
\n" ); document.write( "\"x+=+2.657\"\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "\"5%5Ex+=+72\" Substitute x = 2.657
\n" ); document.write( "\"5%5E2.657+=+71.995\"
\n" ); document.write( "
\n" );
