 Square root of a matrix

The square root of a matrix \( A \) is another matrix \( B \) such that when multiplied by itself, it yields \( A \). Mathematically, this is expressed as: \[ B^2 = A \] Not all matrices have square roots, and if they do exist, they may not be unique. The existence of a square root depends on several properties of the matrix, such as its eigenvalues. ### Types of Square Roots 1.
