Determination of the explicit formula for each square roots of quadratic matrix order 3 can be determined by applying the Cayley-Hamilton Theorem to its characteristic polynomial. Some examples are given in the application of the explicit formula to determine the square roots of a quadratic matrix order 3.enSquare rootsquadratic matrixCayley-Hamilton Theoremcharacter- istic polynomialAKAR KUADRAT DARI MATRIKS KUADRAT ORDE 3ElfitraArticle
