Here's a demo question, made by Ben McGovern: https://numbas.mathcentre.ac.uk/question/134196/error-demo/

a = 5 and b = 6 are integers. The correct answer to a mathematical expression part is defined as x^{a/b}. The expected answer display shows x^5/6. It should show x^(5/6).

It looks like the rational value 5/6 isn't correctly bracketed as the right-hand operand of ^.
