We must load |
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; |

$showPartialCorrectAnswers = 1; UNORDERED_ANS( $answer1->cmp(), $answer2->cmp(), $answer3->cmp(), ); |
Answer Evaluation:
We use $showPartialCorrectAnswers = 0; install_problem_grader(~~&std_problem_grader); |
