Given that log_2 x=5, evaluate:
\n" ); document.write( "log_2(4x^2)
\n" ); document.write( "-----------
\n" ); document.write( " $\"log%282%2Cx%29+=+5\"$
\n" ); document.write( "x = 2^5 = 32
\n" ); document.write( "-------
\n" ); document.write( " $\"log%282%2C4%2A32%5E2%29+=+log%282%2C4096%29\"$
\n" ); document.write( "= $\"log%282%2C2%5E12%29\"$
\n" ); document.write( "=12 \n" ); document.write( "

\n" );
