N varies jointly with the square root of p and the cube of q. If n=72 when p=3 and q=2, find n when p=-4 and q=1/2.
~~~~~~~~~~~~~~~~~~~~~~~~
When a problem of this type says that N varies jointly as the square root of "p",
it is usually assumed that p is non-negative real number - then the real value does exist.
With negative "p" (as -4 in your question), square root of negative "p" does not exist as a real number.
Therefore, your problem, as it is posed in the post, does not make sense.
