PG problem file Explanation

Problem tagging data

Problem tagging: 

DOCUMENT();

loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"AnswerFormatHelp.pl",
"unorderedAnswer.pl",
);

TEXT(beginproblem());

Initialization: We must load unorderedAnswer.pl. 

Context("Numeric")->variables->add(y=>"Real",z=>"Real");

$a = random(2,9,1);

$answer1 = Compute("x^$a");
$answer2 = Compute("y^$a");
$answer3 = Compute("z^$a");

Setup: 

Context()->texStrings;
BEGIN_TEXT
Rewrite the following expression without parentheses.  
Simplify your answer as much as possible, and assume 
that all variables are positive.
$BR
$BR
\( (xyz)^{$a} = \) 
\{ ans_rule(5) \}
\( \cdot \)
\{ ans_rule(5) \}
\( \cdot \)
\{ ans_rule(5) \}
\{ AnswerFormatHelp("formulas") \}
END_TEXT
Context()->normalStrings;

Main Text: 

$showPartialCorrectAnswers = 1;

UNORDERED_ANS( 
$answer1->cmp(), 
$answer2->cmp(), 
$answer3->cmp(),
);

Answer Evaluation: We use UNORDERED_ANS( checker1, checker2, ...); to evaluate the answers. It is possible to withhold feedback and credit until everything is correct by using the standard problem grader, which awards no partial credit and full credit only when everything is correct. 

$showPartialCorrectAnswers = 0;

install_problem_grader(~~&std_problem_grader);

Solution explanation goes here.
END_SOLUTION
