Setup: We have a some code to display the answer blanks nicely in different modes, which you shouldn't need to change except perhaps the width for each answer blank. |
BEGIN_PGML Rewrite the following using a single exponent. [$showpower]*** END_PGML |
Main Text:
We insert the nicely formatted answer blanks using |
$showPartialCorrectAnswers = 1; ANS( $base->cmp() ); ANS( $exponent->cmp() ); |
Answer Evaluation:
Because the answer blanks are traditional |
