a logarithm is an exponent that some base is raised to to get some number\r

\n" ); document.write( "\n" ); document.write( "in this case \"2%5Ex=1%2F8\" where x is the logarithm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since 8=2^3 ... \"2%5Ex=1%2F2%5E3\" or (using rules for exponents) \"2%5Ex=2%5E-3\" ... so x=-3
