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. |
Context()->texStrings; BEGIN_TEXT Rewrite the following using a single exponent. $BR $BR $showpower END_TEXT Context()->normalStrings; |
Main Text:
We insert the nicely formatted answer blanks using |
$showPartialCorrectAnswers = 1; ANS( $base->cmp() ); ANS( $exponent->cmp() ); |
