Uncertainty of the centripetal force

A lab experiment was performed to find the centripetal force on a rotating body which measured mass(m), frequency(n), and radius(r).  It was found that Fc=4Π2n2mr.  How do I write an expression for the uncertainty of the centripetal force?  Thank you

You can use the differential dF as the uncertainty, but you need to use the product rule to compute it, which gives you 3 terms.
