$\"10%5Ex=+1000\"$
\n" ); document.write( " $\"log%28%2810%5Ex%29%29=1og%281000%29\"$ Log of both sides.
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "My answer is 3.
\n" ); document.write( "Correct.
\n" ); document.write( " $\"10%5E%282x%2B1%29+=3\"$
\n" ); document.write( " $\"log%28%2810%5E%282x%2B1%29%29%29=log%283%29\"$ Log both sides.
\n" ); document.write( " $\"2x%2B1=+.4771\"$
\n" ); document.write( " $\"2x=+-.5229\"$ Subtract 1 from both sides and divide by 2.
\n" ); document.write( " $\"x=-.2614\"$
\n" ); document.write( "My answer is x=.2385
\n" ); document.write( "Incorrect.
\n" ); document.write( " $\"e%5E%283y%29=1\"$
\n" ); document.write( " $\"ln%28e%5E%283y%29%29=ln%281%29\"$ Natural log of both sides.
\n" ); document.write( " $\"3y=0\"$ Divide by 3.
\n" ); document.write( " $\"y=0\"$
\n" ); document.write( "My answer is x=.7675
\n" ); document.write( "Incorrect. \n" ); document.write( "

\n" );
