Third-order determinant
WebSince, each element of is either 1 or −1. ∴The value of the determinant cannot exceed 6. Clearly, the value of is 6 when the value of each term in the first bracket is 1. And the value of each term in the second bracket is −1. But a 1b 2c 3=a 3b 1c 2=a 2b 3c 1=1, implies that the product of the nine elements of the determinant is 1.
