Evaluate the following expression :\r
\n" ); document.write( "\n" ); document.write( " $\"+log%283%2C36%29+-+4log%289%2C30%29+%2B+16log%2881%2Csqrt%2815%29%29+\"$
\n" ); document.write( "----------
\n" ); document.write( "Convert to all base 3
\n" ); document.write( "eg, $\"log%289%2C30%29+=+log%283%2C30%29%2Flog%283%2C9%29+=+log%283%2C30%29%2F2\"$
\n" ); document.write( "--> $\"log%283%2C30%29+=+2log%289%2C30%29\"$
\n" ); document.write( "---
\n" ); document.write( "And $\"4log%2881%2Csqrt%2815%29%29\"$ = $\"log%283%2Csqrt%2815%29%29\"$
