  1. A is a factored result, but it isn't factored completely.
    Notice that 9 - 3c still contains a common factor of 3, so you have to factor until you end up with a result that no longer contains any common factor

    so,
    81 - 27p
    = 27(3 - p) , which is B

    you can always check your answer but expanding it
    Notice that both A and B give you the original result.

    Most textbooks label these type of questions with:
    Factor fully , or, factor completely so you must arrive at a "best" answer.

  2. 81 = 27 ∙ 3

    81 - 27 p =

    27 ∙ 3 - 27 p =

    27 ( 3 - p )

    Answer B

    In google type:
