Determinant Multiplication Formula

Formula
$$\det(C) = \det(A) \times \det(B) $$

Where:

  • $$A$$ and $$B$$ are square matrices of the same size
  • $$\det(A)$$ is the determinant of matrix $$A$$
  • $$\det(B)$$ is the determinant of matrix $$B$$
  • $$\det(C)$$ is the product of their determinants

Determinant Multiplication – Calculation Example

$$A = \begin{bmatrix} 2 & 3 \\ 1 & 4 \end{bmatrix}, \quad B = \begin{bmatrix} 0 & 5 \\ 6 & 7 \end{bmatrix}$$

$$\det(A) = (2 \cdot 4) – (3 \cdot 1) = 8 – 3 = 5 $$

$$\det(B) = (0 \cdot 7) – (5 \cdot 6) = 0 – 30 = -30$$

$$\det(C) = \det(A) \times \det(B) = 5 \times (-30) = -150$$

The product of determinants corresponds to the determinant of the product matrix:
$$\det(A \times B) = \det(A) \times \det(B)$$

This property is important in linear algebra and matrix theory, particularly in simplifying matrix product operations. Our calculator ensures accurate and fast determinant multiplication.
