IDZ 1.1 is a linear algebra task that includes several problems.

In the first problem, you need to find minors and algebraic complements for a given determinant and calculate its value in three ways: by expanding the determinant into the elements of the i-th row, expanding the determinant into the elements of the j-th column and first obtaining zeros in the i-th row, where i=4 and j=1.

In the second problem, two matrices A and B are given, and it is necessary to perform several operations on them: find the product of AB, the product of BA, the inverse of matrix A, the product of A and the inverse of matrix A, and the product of the inverse of matrix A and matrix A.

The third task does not specify what to do, so there is no task description.

The fourth task also has no description.
