It means that you have found a way to trigger the error detection mechanism in the symbolic processor (mupad) of your Mathcad 15.

If you are curious about the answer to your expression (Mathcad 11/Maple):

I find the simple answer of factor better:

    Many thanks, Luc.

    But I'm curious about the answer to my expression of (Mathcad 11/Maple):

    PARI failure! ( ' ).PNG

    You sure already found out that its the last modifier ("factor") which throws that error:

    Would be interested to see how the current muPad (owned by MathWorks now, makers of MatLab) deals with this expression.

     

    However, I am very surprised and wonder where you still get this unbridled confidence that Mathcad could actually be able to simplify your expressions in the desired way. 🙂

     

    Here are the result of Prime 10 (symbolic processor is freeCAS/Axiom)

    And in case you are interested, here is what "uncle Wolfram" is able to come up with:

    simplification by Wolfram|Alpha
