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.

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 $showpower.

$showPartialCorrectAnswers = 1;

ANS( $base->cmp() );
ANS( $exponent->cmp() );

Answer Evaluation:
