Problem with a question marked incorrectly #301

Closed BillFoster closed 10 years ago

See https://numbas.mathcentre.ac.uk/question/2055/differentieren-e-macht-ln/

The third part asks for a quotient to be input. I have tried this many times, putting the correct answer but it keeps on being marked as incorrect and I can't see why. I have created a question https://numbas.mathcentre.ac.uk/question/2068/testprob/

which has the same type of input and all other attributes etc the same - but this is marked correctly.

The original question had an x^2 term on top instead of x. As far as I can tell, that's the only problem. I've made a copy of the question with the correct correct answer, and it works: https://numbas.mathcentre.ac.uk/question/2088/christians-copy-of-differentieren-e-macht-ln/

How did I not spot that!
