\"log+%28%281%2F%2810%5E-3%29%29%29%2Blog+%2810%5E4%29\"
\n" ); document.write( "Since \"%281%2F%2810%5E-3%29%29+=+%2810%5E3%29\", the general rule is \"x%5E%28-1%29=%281%2Fx%29\"
\n" ); document.write( "\"log+%28%2810%5E3%29%29%2Blog+%28%2810%5E4%29%29\"
\n" ); document.write( "\"log+%28%2810%5E7%29%29\"
\n" ); document.write( "Since \"log+%28%2810%5E7%29%29\" means the exponent on 10 that produces \"10%5E7\",
\n" ); document.write( "\"log+%28%2810%5E7%29%29\"=7
