\n" ); document.write( "Change the \"2\" to \"log base 10 of some number\": 2 = log base 10 of 100.

\n" ); document.write( "Since the problem is in the standard base 10, we don't need to keep writing \"base 10\". Then

\n" ); document.write( "

\n" ); document.write( "Then, since log(A)=log(B) means A=B,

\n" ); document.write( "\"x%2B4+=+5x\"
\n" ); document.write( "\"4x+=+4\"
\n" ); document.write( "\"x+=+1\"

\n" ); document.write( "
