pow

◼ pow[expr, i] raises the expression expr to the i-th power using the non-commutative multiplication nc.

◼ pow is defined only for nonnegative integers i.

◼ Function Power is best avoided, although a rule is defined for Power[expr,i] expressions where expr is an operator expression.

◼ See also: snegSeries, superkomutator, superantikomutator.
