This PG code shows how to put an answer blank in the exponent.

PG problem file	Explanation
Problem tagging data	Problem tagging:
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "PGcourse.pl", "unionTables.pl", ); TEXT(beginproblem());	Initialization:
Context("Numeric")->variables->are(a=>"Real",b=>"Real"); $n = random(3,9,1); # TeX $expression = "a^{$n} b^{$n}"; # MathObjects $base = Formula("a*b"); $exponent = Formula("$n"); # # Display exponents nicely # $w1 = 10; # width of 1st answer blank $w2 = 10; # width of 2nd answer blank Context()->texStrings; if ($displayMode eq 'TeX') { $showpower = "$ \displaystyle $expression = (" . ans_rule($w1) . ")^{" . ans_rule($w2) . "}$"; } else { $showpower = ColumnTable( "$ \displaystyle $expression = \Big( $ " . ans_rule($w1) . " $ \Big) $", ans_rule($w2).$BR.$BR, indent => 0, separation => 0, valign => "BOTTOM" ); } Context()->normalStrings;	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. [$showpower]*** END_PGML	Main Text: We insert the nicely formatted answer blanks using `$showpower`.
$showPartialCorrectAnswers = 1; ANS( $base->cmp() ); ANS( $exponent->cmp() );	Answer Evaluation: Because the answer blanks are traditional `ans_rule`, then we need to use this style of answer checking.
BEGIN_PGML_SOLUTION Solution explanation goes here. END_PGML_SOLUTION ENDDOCUMENT();	Solution:
