document.write( "I know that you need to let one variable equal 0 to solve for the other, but I am completely lost when it comes to the log on what to do! I've heard to cancel it out on one side (when solving for x) you need to change the x of the log (the 4 in this case) to an exponent on the base, but I'm not sure... \n" );
