Power associativity
In mathematics, specifically in abstract algebra, power associativity is the property of a binary operation that integer powers ( x n {\displaystyle x^{n}} ) are well-defined; it implies that x m ∗ x n = x m + n {\displaystyle x^{m}*x^{n}=x^{m+n}} for all positive integers m , n {\displaystyle m,n} . It is a weak form of associativity.
