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

A logarithm of constants and nested powers of one linear L, ln(c (d L^p)^q), is
p q ln(L) + K with K constant wherever it is continuous, since its derivative is
p q L'/L by the chain rule on any branch: named so, Rubi's 3.3
(g + h x)^2 (a + b ln(c (d (e + f x)^p)^q))^3 is a polynomial times a power of
ln(e + f x), answered in a quarter of a second, where as written it was declined after
eleven and twelve gigabytes. The answer is the generic case's, as
SolveByNamingALogarithmLinearInTheVariable(AngouriMath.Entity,AngouriMath.Entity.Variable,System.Boolean)'s is. Only a nested power, which the
rules for ln(c L^n) do not read. Asked as a question of its own.
