but I thought the answer would be :-


q = 1/k * p^(1/3)


k is the constant

Re: inversely proportional

Because it's inverse proportion the term with p must be at the bottom of a fraction.

As k is just a number, writing 1/k doesn't satisfy the question.  It's the p term that has to be at the bottom of the fraction.

I've no idea where 8 comes from.  To change k into a number you have to be told one pair of q and p values.
