Prove each theorem using 3x3 determinant.
Theorem 4: If all elements in any row (or column) are multiplied by a number, the determinant is also multiplied by this number. Theorem 5: If any two rows (or columns) are the same or proportional, the determinant is zero. Theorem 6: If we express the elements of each row (or columns) as the sum of two terms, then the determinant can be expressed as the sum of two determinants having the same order.
