Ferrero and Washington observed the joint equidistribution of digits of p-adic integers, which describes the growth of class number in a certain tower of number fields. We reprove the main equidistribution instance, based on the ergodicity of a p-adic skew extension dynamical system that can be suitably identified with Bernoulli shift (joint with Bharathwaj Palvannan).
