To evaluate:\r
\n" ); document.write( "\n" ); document.write( "9 to the negative power of 2\r
\n" ); document.write( "\n" ); document.write( "Looks like this:\r
\n" ); document.write( "\n" ); document.write( " $\"9%5E-2\"$ \r
\n" ); document.write( "\n" ); document.write( "Now, you cannot leave your answer in that form, you have to change it.
\n" ); document.write( "Here's how:\r
\n" ); document.write( "\n" ); document.write( "Move the 9 to the denominator, this changes the sign, power of 2 to positive
\n" ); document.write( " $\"1%2F9%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( "To simplify further, multiply 9 x 9 (power of 2) to equal 81:\r
\n" ); document.write( "\n" ); document.write( " $\"1%2F81\"$ \n" ); document.write( "

\n" );
