OWL question - Roots

There have been a few people asking about the "Roots" question in OWL and I think the confusion may be coming from the way it's worded.  It sounds as if you will get a very large or very small number as an answer that will require scientific notation to answer, but the 3-4 times I've tried the question, my correct answer has always been easily expressed without scientific notation, answers like "4.293" and "0.271".

Simplest help = just evaluate the mathematical expression given in the problem and type in the answer you get.
