Abstract: Derivation of Baker- Hausdorff formula using the matrix representation is a simple method. The derivation does not refer to the differential for a parameter. Furthermore,the matrix representation for Baker- Hausdorff formula is more useful to treat the specific physical problem.

Key words: representation, operator's matrix representation, Baker-Hausdorff formula
