SolveByDistributingWholePowersOfProducts​(AngouriMath.​Entity,​AngouriMath.​Entity.​Variable,​System.​Boolean)

A whole power of a product in which the variable stands beside a constant, written
as the product of the powers: (c x)^2 is c^2 x^2, exact for a whole
power over the complex numbers. That is the spelling the parser gives the inverse
hyperbolic secant and cosecant -- acsch(c x) is
ln(1/(c x) + sqrt(1/(c x)^2 + 1)) -- and every rule that reads a polynomial in
x read (c x)^2 as a power of something that is not one: x acsch(c x) was declined where x acsch(2 x) was answered, the numeric coefficient having
been folded on the way. A symbolic constant beside the variable only: a numeric one
is folded by the rules already, and rewriting for it re-asked every sub-integrand
with a (2 u)^3 in it -- Welz's 67 went from 4 s to 34. Asked as a question of
its own. Rubi's 7.5.1 and 7.6.1.
