You can put this solution on YOUR website!
The difference is that log -m+2=4 does not mean anything, but that log(-m+2)=4 ALMOST means something. You need to already know, or be able to indicate, the base for the logarithm.\r

\n" ); document.write( "\n" ); document.write( "Letting b be the base then the second thing you wrote should look like $\"log%28b%2C%28-m%2B2%29%29=4\"$ . This now means something. Logarithm of $\"-m%2B2\"$ is 4; or arranged in exponential form, knowing the still variable base of b, $\"b%5E4=-m%2B2\"$ . \n" ); document.write( "
