Module Type NZPowProp
(Import A : NZOrdAxiomsSig')
(Import B : NZPow' A)
(Import C : NZMulOrderProp A).
Hint Rewrite pow_0_r pow_succ_r : nz.
(** Power and basic constants *)
Hint Rewrite pow_1_r pow_1_l : nz.
Hint Rewrite pow_2_r : nz.
(** Power and nullity *)
(** Power and addition, multiplication *)
(** Positivity *)
(** Monotonicity *)
(** NB: since 0^0 > 0^1, the following result isn't valid with a=0 *)
(** Injectivity *)

Lemma pow_inj_l : forall a b c, 0<=a -> 0<=b -> 0<c ->
a^c == b^c -> a == b.
