document.write( "Question 1099279: I have a problem: $\"ln%28x%29=5163\"$ . I got the correct answer on a problem similar to this: $\"ln%28x%29=-4.16\"$ . My process for the latter problem was to rewrite it as $\"e%5E-4.16=x\"$ and then simplified it to $\"1.56x10%5E-2=x\"$ . My answer book indicated that answer as correct. When I tried to apply the same formula to the former problem, the calculator put up a notification saying ERROR. What was I doing wrong? Do I have the wrong formula and just got the second problem right by accident? I am using a CASIO fx-9750GII. Thanks for taking the time to help! \n" ); document.write( "
