We prove an elementary formula about the average expansion of certain products of 2 by 2 matrices. This permits us to quickly re-obtain an inequality by M. Herman and a theorem by Dedieu and Shub, both concerning Lyapunov exponents. This is a work of A. Avila and J. Bochi. &nbsp;<a href="https://link.springer.com/article/10.1007/BF02785853">https://link.springer.com/article/10.1007/BF02785853</a>
