The document contains 29 math problems involving polynomial multiplication and division. Students are asked to calculate the products and quotients of polynomials such as (a3 - 3b), (-9x)(-12xy + 5), and (4mn)(5m2n + 6mn2). They are also asked to perform division of polynomials like 18x5 ÷ 9, (-13p5q3) ÷ (-13p2q), and (-15ab4 + 3a2b2 - 21b3) ÷ 3b2. The problems cover a range of operations with monomials and polynomials of varying degrees.

1. The determinants of matrices A, B, and C are calculated. The determinant of ABC is equal to the determinant of CBA.
2. The determinant of the matrix AB is calculated. When the dimensions of A and B are multiplied, the determinant is the product of the determinants.
3. A system of linear equations is solved using determinants and Cramer's rule. The solutions are found to be x=0, y=1, z=2.
