Assume the problem is:
\n" ); document.write( " $\"2%5E%28%283-x%29%29\"$ = 565
\n" ); document.write( "find the log of both sides
\n" ); document.write( " $\"log%282%5E%28%283-x%29%29%29\"$ = $\"log%28565%29\"$
\n" ); document.write( "the log equiv of exponents
\n" ); document.write( "(3-x)*log(2) = log(565)
\n" ); document.write( "3 - x = $\"log%28565%29%2Flog%282%29\"$
\n" ); document.write( "3- x = 9.1421
\n" ); document.write( "-x = 9.1421 - 3
\n" ); document.write( "-x = 6.1421
\n" ); document.write( "x = -6.1421
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this on a calc: enter: 2^(3-(-6.1421)) results in 564.997 ~ 525 \n" ); document.write( "

\n" );
