The logarithm, base 2, of 1/16.\r
\n" ); document.write( "\n" ); document.write( "In other words: What exponent of 2 is 1/16?\r
\n" ); document.write( "\n" ); document.write( "Finding a logarithm is basically the opposite of finding a power.\r
\n" ); document.write( "\n" ); document.write( "In other words: Solve this equation for \"y\" : \"2%5Ey+=+1%2F16\"\r
\n" ); document.write( "\n" ); document.write( "Here are some examples of exponents of 2:\r
\n" ); document.write( "\n" ); document.write( "\"2%5E5+=+32\"
\n" ); document.write( "\"2%5E4+=+16\"
\n" ); document.write( "\"2%5E3+=+8\"
\n" ); document.write( "\"2%5E2+=+4\"
\n" ); document.write( "\"2%5E1+=+2\"
\n" ); document.write( "\"2%5E0+=+1\"
\n" ); document.write( "\"2%5E-1+=+1%2F2\"
\n" ); document.write( "\"2%5E-2+=+1%2F4\"
\n" ); document.write( "\"2%5E-3+=+1%2F8\"
\n" ); document.write( "\"2%5E-4+=+1%2F16\"
\n" ); document.write( "That last one is the one you want ...\r
\n" ); document.write( "\n" ); document.write( "The answer is: \"log_2+%281%2F16%29+=+-4\"
\n" ); document.write( "
