the associative property only regroups the factor -- it does not reorder them.
To say that (mq)*n = (nm)*q requires the commutative property, which allows you to assert that
mq*n = mn*q = nm*q
The mq value can be used as a group, which allows
(mq)*n = n*(mq)
using the commutative property
The espionage is use only an associative property to rewrite the expression: (mq) * n
My teacher says the correct answer is m * (qn) but could the answer also be (nm) * q or m * (mq) or q * (mn)?
