Question 5

Let $A,M,N,P,S,W$ be real numbers such that
$$M=S^1W^2A^3P^4,\qquad N=P^1A^2W^3S^4.$$
Suppose $W\times A\times S\times P=1331^{1/15}$. What is $M\times N$?

Interpretation: The source question has a faint/missing first factor before ×A×S×P. We restore W, as explicitly used in the source solution.
