$\"75=100-100e%5E%28-0.01x%29\"$
\n" ); document.write( " $\"100e%5E%28-0.01x%29=100-75\"$
\n" ); document.write( " $\"100e%5E%28-0.01x%29=25\"$
\n" ); document.write( " $\"e%5E%28-0.01x%29=25%2F100\"$
\n" ); document.write( " $\"e%5E%28-0.01x%29=0.25\"$
\n" ); document.write( " $\"-0.01x=ln%280.25%29\"$
\n" ); document.write( " $\"0.01x=-ln%280.25%29\"$
\n" ); document.write( " $\"x=-ln%280.25%29%2F0.01\"$ <--> $\"x=-ln%281%2F4%29%2F0.01\"$ <--> $\"x=ln%284%29%2F0.01\"$ <--> $\"x=100ln%284%29\"$
\n" ); document.write( "So $\"highlight%28x=100ln%284%29%29\"$ is an elegant way to write the exact result,
\n" ); document.write( "but $\"x=-ln%280.25%29%2F0.01\"$ would allow you to calculate an approximate result with a calculator. \n" ); document.write( "
